Cold email software: a buyer's guide to 15 tools in 2026
15 cold email tools grouped by type and compared on price, warm-up, follow-ups, LinkedIn and free plans, plus sending limits and real campaign costs.
The best cold email software is the one that matches your volume and your channels. For sending a lot from many mailboxes, Instantly is the safest pick. If you also prospect on LinkedIn, lemlist does email and LinkedIn in one sequence. If you send from a few established mailboxes and want to pay as little as possible, Mailpitcher (that’s us) costs $7.99 a month and its Pro plan lets Claude or any MCP client run your outreach. Free plans that can actually send exist too: Hunter, Mailmeteor, Snov.io and Apollo.io.
We checked every price and feature below on the vendor’s own pricing page on 12 October 2026.
Emails per day, all mailboxes–
Follow-ups count as if nobody replies, and the days are sending capacity only: the wait between a first email and its follow-up adds to that. Mailbox providers have their own limits too: about 500 a day for personal Gmail and 2,000 for Google Workspace.
Our top three
- Instantly: unlimited mailboxes and warm-up on every plan, from $47 a month. Built for volume.
- lemlist: email, LinkedIn, calls and a lead database in one tool, from $69 a month.
- Mailpitcher: the lowest price on this list, with an MCP server on Pro so an AI assistant can draft, send and run campaigns.
Pick by situation
- You send thousands of emails a week from many domains: Instantly or Smartlead.
- You prospect on LinkedIn as well as email: lemlist, Reply.io or QuickMail.
- You’re a freelancer or small agency on a budget: Mailpitcher, or Mailmeteor if you only send from Gmail and don’t need follow-ups.
- You have no list yet: Apollo.io, Hunter or Snov.io, which find the addresses and send.
- You want a simple sequencer with clear limits: Woodpecker, Saleshandy, Mailshake or QuickMail.
- Your budget is zero: Hunter Free, Mailmeteor Free or Snov.io’s free plan, to test your message before you pay.
What cold email software actually does
Cold email software sends personal-looking emails to people who don’t know you yet, one at a time, from mailboxes you own. It is not a newsletter tool. Newsletter platforms send one message to thousands of subscribers who opted in, from shared servers. Cold email tools connect to your Gmail, Outlook or other mailbox and send each email as if you had written it by hand, so it arrives as a normal message from a person.
Under the hood, almost every tool does the same five jobs:
- Build the listImport a CSV or pull contacts from a lead database, then verify the addresses.
- Write the sequenceA first email plus two or three follow-ups, with merge tags for names and details.
- Pace the sendingEach mailbox sends a capped number per day, spread across working hours.
- Stop on replyAnyone who answers leaves the sequence; bounces and opt-outs are suppressed.
- Handle repliesReplies land in an inbox where you answer and track who agreed to what.
The differences sit in the details. How many mailboxes can you connect before the price goes up? Does the tool pause itself when bounces climb? Do follow-ups land in the same thread? Can you find new contacts inside the tool, or do you bring your own list? And when someone replies, do you answer in the tool, in your normal inbox, or in both?
A campaign usually looks like this: 200 to 2,000 prospects, a first email and two or three follow-ups a few days apart, sent from one to ten mailboxes at 30 to 100 emails per mailbox per day. The software’s job is to make that pace automatic and to stop the moment someone answers.
How to evaluate cold email software
Headline prices hide most of the differences. These five areas decide whether a tool fits.
Deliverability
Your domain’s reputation is the asset you’re protecting. A good tool caps how many emails each mailbox sends per day, spreads them out, and stops a campaign if something goes wrong. Look for:
- A daily cap per mailbox that you can set, not only an account-wide limit.
- Warm-up, if you send from new domains. Warm-up networks exchange emails between member mailboxes to build a sending history. Instantly, Smartlead, lemlist, Saleshandy, Mailshake and QuickMail include it; others offer a few slots or charge per mailbox.
- Bounce protection. Sending to dead addresses is one of the fastest ways to hurt a domain. Some tools verify addresses before sending; some pause campaigns when bounces rise.
- Mailbox rotation. Spreading a campaign across several mailboxes keeps each one at a modest volume. Our cold email deliverability guide covers when that’s fine and when it becomes a way to dodge filters.
Sequences and follow-ups
Busy people often answer the second or third email, so follow-ups matter more than any other feature. They should go in the same thread and stop the moment someone replies. Nothing damages a relationship faster than a “just bumping this” after someone already said yes. Check whether follow-ups are on the entry plan: GMass and Mailmeteor both reserve them for higher tiers.
Personalization
At minimum you want merge tags from your CSV columns, with fallbacks for empty fields and a check that catches unfilled tags before anything sends. Some tools add AI-written first lines, custom images or landing pages. These help on some lists and add noise on others; a specific, relevant first sentence you wrote yourself usually beats a generated one.
Integrations
If you work in a CRM, check that the tool syncs contacts and replies to it, and on which plan. Smartlead’s API and CRM start on Pro, Woodpecker’s API is a $20 add-on, and QuickMail’s API is not on Starter. On the other side, an AI assistant connection (MCP) is now listed by lemlist and by Mailpitcher, so you can ask Claude to draft or send through your mailboxes.
Analytics
Reply rate is the number that matters. Open tracking has become unreliable because many mail apps preload images, and tracking pixels can themselves hurt deliverability. Click tracking, A/B tests and per-step reports are useful once you send enough volume to compare versions; below a few hundred emails a week, the differences you see are mostly noise.
Here is how the 15 tools compare on the six features buyers ask about most. “Not listed” means the pricing page doesn’t say, so ask the vendor before you rely on it.
| Feature | Unlimited mailboxes | Warm-up included | Follow-ups on entry plan | LinkedIn steps | Lead database | Free plan |
|---|---|---|---|---|---|---|
| Instantly | Yes | Yes | Yes | No | Partly: paid credits | No: trial |

| Mailshake | No: 1 on Starter | Yes | Yes | not listed | Partly: 50 credits | No: no trial |
| QuickMail | Yes | Yes | Yes | Yes | No | No: trial |
Two patterns stand out. The volume tools (Instantly, Smartlead, QuickMail) bundle unlimited mailboxes and warm-up, while the budget and data tools cap mailboxes on their cheapest plans. And only lemlist, Reply.io, Snov.io, Woodpecker and QuickMail list LinkedIn steps, most of them as a paid add-on or a higher plan.
The tools, grouped by what they’re built for
Most “best of” lists rank everything in one line. That hides the fact that a high-volume sender and a Gmail add-on are different products for different people. We grouped the 15 tools by what they’re built for and gave each the same treatment: price, then pros and cons.
| Mailmeteor | $5.99, Starter, no follow-ups |
|---|---|
| Mailpitcher | $7.99, Solo, 3 mailboxes |
| Mailshake | $29, Starter, 1,500 sends |
| GMass | $29.95, Standard, no follow-ups |
| Woodpecker | $35, 500 prospects |
| Smartlead | $39, Base |
| Snov.io | $39, Starter; free plan too |
| Saleshandy | $41, Starter |
| Instantly | $47, Growth |
| Hunter | $49, Starter; free plan too |
| QuickMail | $49, Starter |
| Klenty | $50, Starter, billed annually |
| Reply.io | $59, Email Volume |
| lemlist | $69, Email |
Monthly billing unless noted. Apollo.io is left out because its paid prices couldn't be confirmed. Checked 12 October 2026 on each vendor's pricing page.
High-volume senders
These tools assume you send from many mailboxes and domains, often thousands of emails a day. They include unlimited mailboxes and warm-up, and they charge by contacts and emails per month.
Instantly is the volume specialist: every plan includes unlimited email accounts and unlimited warm-up.

- Cons: Base lacks the API and CRM; add-ons are extra and non-refundable; no LinkedIn steps listed; user reviews mention slow support.
Multichannel platforms
These add LinkedIn, calls and sometimes SMS or WhatsApp to the email sequence. They cost more and are often priced per user, which adds up quickly for a team.
lemlist mixes email with LinkedIn, calls and SMS, and includes a lead database and its lemwarm warm-up on every plan. More detail in our lemlist alternatives guide.
- Price: Email $69/month ($55 yearly) with unlimited users and senders; Multichannel $109/month per user ($87 yearly).

- Cons: more expensive than email-only tools; Multichannel is priced per seat with 5 senders per user; data features use paid credits; user reviews mention a learning curve and slow support.
Reply.io splits its pricing into an email-only plan and a multichannel one.
- Price: Email Volume from $59/month; Multichannel from $99/month. LinkedIn on Email Volume is a $69/month add-on per account; calls and SMS $29.
- Pros: unlimited mailboxes on Email Volume, under a fair-use policy; unlimited follow-ups per contact; LinkedIn included on Multichannel; 14-day trial.
- Cons: Multichannel includes 5 mailboxes per user, and extra email accounts cost $29 each; only 50 data credits a month; add-ons stack up fast; no free plan.
Klenty is a sales engagement tool aimed at sales teams that run cadences across email and other channels.

- Pros: high contact and email limits on Starter; multichannel outreach from Growth; phone and email credits on Plus; 14-day trial with no card.
- Cons: prices shown are annual; Growth and Plus are per user; the pricing page doesn’t say whether warm-up is included or how many mailboxes you get; no free plan, and the account is deactivated if you don’t upgrade.
Budget and inbox-based tools
These send from mailboxes you already use, often from inside your inbox. They’re cheap and simple, and they suit people who send tens or a few hundred emails a day rather than thousands.
Mailpitcher is an email client with cold outreach built in: every mailbox (Gmail, Outlook, Porkbun, GoDaddy or any IMAP host) in one inbox, with campaigns that send from those same mailboxes.
- Price: Solo $7.99/month ($79/year) for up to 3 mailboxes; Pro $12.99/month ($129/year) for unlimited mailboxes and an MCP server. No credits or per-email fees.
- Pros: the lowest-priced paid plan with follow-ups; on Pro, Claude or any MCP client can draft, send and run campaigns within your daily caps; follow-ups that stop on reply, up to 4 on campaigns and 3 on single emails; a daily cap per mailbox, a slower start for new mailboxes and an automatic pause if bounces pass 5%.
- Cons: no lead database or email finder; no open and click tracking (subject-line A/B tests are judged on replies); no warm-up network, so it suits established mailboxes better than fresh domains at volume; no LinkedIn, calls or SMS.
Sequence
Edit emailsFollow-ups go from the same mailbox in the same thread and stop when the contact replies.
Hi {{first_name}}, I enjoyed your post on slow travel in Portugal. Would a guide to off-season train routes suit {{site}}?
GMass runs campaigns from inside Gmail.
- Price: Standard $29.95/month; follow-ups need Premium at $39.95/month.
- Pros: works in the Gmail you already use; A/B tests and API on Premium; inbox rotation on Professional.
- Cons: Gmail only, with one subscription per sending account; its warm-up service has ended; no follow-ups on the cheapest plan; no lead data.

- Cons: no follow-ups on Free or Starter; one sender on the cheaper plans; no lead database; built for mail merge rather than multi-mailbox cold campaigns.
Data plus sending
These started as contact databases or email finders and added sequences later. They make sense if you don’t have a list yet, but the sending side is usually simpler than in dedicated tools.
Apollo.io is a B2B database first, with sequences on top.
- Price: free plan; the pricing page lists Basic at $49/month and Professional at $99.
- Pros: contacts and sending in one tool; a free plan that never expires; credits shared across a team with per-user caps.
- Cons: the free plan sends from Gmail only; credits don’t roll over; warm-up uses credits; user reviews question data accuracy outside the US.
Hunter is best known for finding email addresses, and its sequences make it a simple all-in-one for beginners.
- Price: free plan with 50 credits and 1 mailbox; Starter $49/month ($34 yearly) with 3 mailboxes and 2,000 credits.
- Pros: a free plan that actually sends; email finder and verification built in; unlimited team members.
- Cons: the free plan sends 15 emails a day by default; only 3 mailboxes on Starter; sequences are basic for advanced users; credits don’t roll over.
Snov.io combines an email finder, verification, warm-up and drip campaigns.
- Price: free plan with 50 credits and 100 recipients a month; Starter $39/month for 1,000 credits and 5,000 recipients; Pro S $99/month. LinkedIn automation $69/month per slot.
- Pros: a free plan that renews every month; unlimited follow-ups, which don’t count against recipients; 3 warm-up slots on Starter; finder and sender in one place.
- Cons: 3 mailboxes on Starter; LinkedIn is a separate $69 slot; low credits on the free plan; the credit system takes time to understand.
Simple sequencers
These do email sequences well without trying to be a database or a LinkedIn bot. They’re the middle ground between the budget tools and the volume platforms.
Woodpecker charges by prospects contacted each month rather than by seat.
- Price: from $35/month for 500 contacted prospects (8,000 emails).
- Pros: unlimited mailboxes and users; email verification included; optional LinkedIn steps ($29/month per account).
- Cons: only 2 free warm-up slots, then $5 per mailbox; the API is a $20/month add-on; the trial stops at 100 emails or 14 days.
Saleshandy is a budget sender with a lead finder built in.
- Price: Starter $41/month ($34 yearly) for 2,000 active prospects and 6,000 emails.
- Pros: warm-up on all plans; 1,500 lead-finder credits a month; no per-inbox fees.

- Pros: unlimited warm-up on all plans; unlimited sends from Email Outreach; a cheap way in for a single sender.
- Cons: only 1 address and 1,500 sends on Starter; no free trial, payment is collected up front; Data Finder is a $19/month add-on.
QuickMail is popular with agencies for its support and its included warm-up.
- Price: Starter $49/month for 1,000 contacts and 5,000 emails; Growth $99/month; Agency $299/month.
- Pros: unlimited senders, LinkedIn accounts and users on every plan; free warm-up; well-rated support.
- Cons: the trial needs a card; no API on Starter; no lead database.
Sending limits by email provider
Whatever tool you use, your email provider sets the ceiling. These are the providers’ own published limits. Hitting them gets your mailbox paused, so for cold email stay far below.
| Provider | Published limit | Source |
|---|---|---|
| Gmail (personal) | About 500 emails a day; 500 recipients per email | Google Help |
| Google Workspace | 2,000 emails a day per user; 500 on trial accounts; 3,000 external recipients a day | Google Workspace Help |
| Outlook.com (Microsoft 365 subscribers) | 5,000 recipients a day; 1,000 a day to people you’ve never emailed; lower for free accounts | Microsoft Support |
| Microsoft 365 business (Exchange Online) | 10,000 recipients a day; 30 messages a minute | Microsoft Learn |
The Outlook.com row matters most for cold email: 1,000 “non-relationship” recipients a day is the real cap when everyone on your list is new. Microsoft also says new accounts start with a lower quota that rises as they build a history. Google counts its limits over a rolling 24 hours. In practice, most senders keep each mailbox at 50 to 100 cold emails a day and add mailboxes rather than push one harder.
Cold email tool or cold email agency?
A tool gives you control and costs tens of dollars a month. You write the emails, build the list and answer the replies. An agency does some or all of that for you and charges for the time, usually as a monthly retainer or per meeting booked.
Use a tool if:
- You know your offer and your buyers well enough to write to them yourself.
- Replies need a personal answer from you, as in sales by founders, freelancing, PR and link building.
- Your budget is under a few hundred dollars a month.
Consider an agency if:
- Nobody on your team has time to write, send and follow up every week.
- You need a lot of new domains and mailboxes set up and warmed quickly.
- You’d rather pay per result than learn the process.
Some former software vendors have moved into services. Respona, for example, now sells done-for-you link placements at $100 to $500 each rather than software. If you take the agency route, ask whose domains they send from, who owns the list afterwards, and how they handle opt-outs, because their mistakes land on your brand.
What a cold email campaign costs
The software is usually the smallest cost. You’ll also pay for mailboxes (from your email provider), possibly extra domains, contact data, and your own time. Here are three worked examples using the prices above.
Example 1: a freelancer contacting 1,000 new prospects a month. One first email and three follow-ups is at most 4,000 emails, fewer once people reply. Sent from three established mailboxes at 70 a day each, that’s about 20 working days.
| Mailpitcher | $7.99, Solo, 3 mailboxes |
|---|---|
| Smartlead | $39, Base, 2,000 contacts / 6,000 emails |
| Saleshandy | $41, Starter, 6,000 emails |
| Instantly | $47, Growth, 1,000 contacts / 5,000 emails |
| Mailshake | $49, Email Outreach, 2 addresses |
| Reply.io | $59, Email Volume |
| lemlist | $69, Email |
Cheapest plan whose stated limits cover the example. Mailbox costs from your email provider are extra. Checked 12 October 2026.
Mailpitcher Solo covers this at $7.99 because it has no contact or email limit, only your per-mailbox caps. Instantly Growth fits exactly within its 1,000 contacts and 5,000 emails. Smartlead Base and Saleshandy Starter have room to spare. Mailshake Starter’s 1,500 sends a month is too few, so you’d need Email Outreach at $49.
Example 2: an agency sending 20,000 emails a month from 10 mailboxes. Instantly needs Hypergrowth at $97, since Growth stops at 5,000 emails. Smartlead needs Pro at $94. Mailpitcher Pro at $12.99 covers unlimited mailboxes; at the default cap of 100 a day, 10 mailboxes send 1,000 a day, so 20,000 takes about 20 sending days. You’d still need contact data from somewhere, which the data tools sell as credits.
Example 3: testing a message for free. Mailmeteor Free sends 50 emails a day and 500 a month, but no follow-ups. Snov.io’s free plan covers 100 recipients with follow-ups. Hunter Free sends 15 a day by default from one mailbox. If you already pay for Google Workspace, Business Standard and higher editions include a built-in mail merge for up to 1,500 recipients a day, with no follow-ups. That’s enough to learn whether anyone replies before you pay for anything.
Is cold email legal?
In the US, B2B cold email is legal under CAN-SPAM if you identify yourself, don’t use misleading subject lines, include a physical address and honor opt-outs. In the EU and UK the rules vary by country: some allow B2B cold email to business addresses under legitimate interest, while others, such as Germany, generally require prior consent. Cold email to consumers is far more restricted. Check the rules where your recipients are, and treat this as a starting point rather than legal advice.
Whichever tool you pick, keep one do-not-contact list across all your campaigns, so someone who opted out of one campaign isn’t emailed by the next.
Cold email best practices
- Keep the list narrow. 200 people your offer is clearly relevant to beat 2,000 who might care.
- Verify addresses before sending. Bounces hurt your domain more than anything you write.
- Write short. Three to five sentences: who you are, why them, what you’re asking for.
- Follow up two or three times, then stop. Space follow-ups a few days apart, in the same thread.
- Send slowly from established mailboxes. 50 to 100 a day per mailbox, with new mailboxes starting lower.
- Make opting out easy, and honor it everywhere, not only in the current campaign.
- Measure replies, not opens. Reply rate tells you whether the message works.
Questions people ask
How do you do cold emails?
Pick a narrow list of people your offer is relevant to, find and verify their work addresses, and write a short email that explains why you're contacting them specifically. Send it from your own mailbox at a modest daily pace, follow up two or three times in the same thread, and stop as soon as someone replies or asks you to.
Is cold emailing illegal?
In the US, B2B cold email is legal under CAN-SPAM if you identify yourself, don't use misleading subject lines, include a physical address and honor opt-outs. In the EU and UK the rules vary by country: some allow B2B cold email to business addresses under legitimate interest, while others, such as Germany, generally require prior consent. Cold email to consumers is far more restricted, so check the rules where your recipients are.
Which tool is commonly used for email automation?
It depends on who you're emailing. Newsletters to people who signed up go through email marketing platforms; cold outreach to people who haven't goes through cold email tools such as Instantly, lemlist, Smartlead or Apollo.io, which send from your own mailboxes and stop following up when someone replies.
What is cold email software?
It's a tool that sends personalized emails to people who don't know you yet, usually from your own mailboxes, with merge tags, automatic follow-ups that stop when someone replies, sending limits to protect your domain, and a place to see the replies.
Is there free cold email software?
Yes, with low limits. Hunter has a free plan with 1 connected mailbox and 50 credits a month, Mailmeteor sends up to 500 emails a month (50 a day) for free, Snov.io has a free plan with 100 recipients, and Apollo.io has a free plan that sends from Gmail. Instantly, Smartlead and lemlist only offer free trials.
What is the cheapest cold email tool?
Among paid plans, Mailpitcher starts at $7.99 a month and Mailmeteor at $5.99, though Mailmeteor's entry plan has no follow-ups. Most dedicated cold email platforms start between $29 and $59 a month.
How many cold emails can I send per day?
It depends on your mailbox as much as the software. Google limits consumer Gmail to about 500 emails a day and Google Workspace to 2,000. For cold outreach, staying well below that, often 50 to 100 a day per mailbox, protects your sending reputation.
Do I need warm-up for cold email?
New domains and mailboxes benefit from a gradual start. Instantly, Smartlead, lemlist, Saleshandy, Mailshake and QuickMail include warm-up. Mailpitcher instead limits new mailboxes to 50 emails a day for three days before its default cap of 100.
