Cold email software sends personalized emails and follow-ups to prospects who don't know you yet, while protecting your inbox's reputation.
The best cold email software for you depends on how you prospect: a big list and lots of email, email plus lead data, several channels at once, or LinkedIn first. Below we compare five tools on sending limits, warmup, lead data and price, checked on each vendor's own pricing page.

What cold email software does
Cold email software is a tool for sending first-contact sales emails at scale. You upload or find a list of prospects, write a short sequence, and the tool sends each step on a schedule, personalizes the details and stops when someone replies. A few terms you'll see:
- Sequence (or campaign). A series of emails, for example a first email and two follow-ups a few days apart.
- Warmup. Slowly building a new inbox's sending history so email providers trust it and don't send your messages to spam.
- Deliverability. How much of your email lands in the inbox instead of the spam folder.
- Sending account (mailbox). An email address the tool sends from. Spreading volume across several accounts keeps each one under safe limits.
- Lead database and credits. A searchable list of business contacts. You usually spend credits to reveal an email address or phone number.
- Multichannel. Mixing email with LinkedIn, calls, SMS or WhatsApp steps in one sequence.
How we chose
We picked cold email and outreach tools with self-serve plans and prices published in US dollars, and read each one's official pricing page: Instantly, lemlist, Reply.io and Dripify on October 15, 2026, and Apollo on October 29, 2026. We haven't tested them hands-on yet, so we can't tell you which one lands the most email in the inbox; we tell you what each plan includes, who it suits and what you pay.
We added Apollo on October 30, 2026, once its plan prices were readable. Waalaxy, another LinkedIn tool, isn't a full pick: on October 29, 2026 its page listed €19, €49 and €69 per user a month without saying which billing period those rates cover. Lusha and RocketReach are mainly contact-data tools (both also list basic email sending), so they're covered below as add-ons.
Instantly: best for high-volume cold email on a budget
Cold email platform that sends from unlimited email accounts with built-in warmup, plus a B2B lead database, email verification, a CRM and AI agents for prospecting and replies.

On the day we checked, the pricing page showed conflicting numbers in places (Hypergrowth at both $97 and $358 a month), so confirm the price at checkout.
Who it's for: Founders, freelancers and agencies who already have a list of prospects and want to send a lot of email from many inboxes without paying per inbox.
Skip it if: You need lead data and LinkedIn steps in the same plan. lemlist or Reply.io bundle more channels.

Need lead data? Tools to pair with a sender
If your sender has no database (Instantly's Outreach plans don't), you can buy contact data separately and upload it. They're mainly contact-data tools. Both also list email sequences, but we compare them here on data, not sending, so we don't rank them above.
| Tool | What you get | Starts at | Free option |
|---|---|---|---|
| Lusha | Emails and phone numbers; an email costs 1 credit, a phone number 5 | $49.90/mo billed monthly, 400 credits a month ($37.45/mo billed yearly) | 40 credits a month |
| RocketReach | Essentials finds emails only; phone numbers start on Pro ($99/mo, $69/mo yearly) | $49/mo billed monthly, 100 lookups a month ($329 a year) | 3 lookups |
| Waalaxy | LinkedIn invitation and message sequences, an email finder and cold email follow-ups | Listed at €19 per user a month; billing period not stated | 14-day trial |
Lusha and RocketReach prices in US dollars; Waalaxy's are shown in euros on the vendor's page. All read October 29, 2026. Lusha's and RocketReach's plan cards load with JavaScript, so we read them in a browser.

Check these before you pay
- What the limit counts. Instantly caps emails and uploaded contacts, lemlist caps emails, Reply.io caps active contacts, Apollo caps data credits per seat and Dripify caps daily LinkedIn actions. Estimate your monthly volume first.
- Lead data costs. A database search is often priced in credits on top of the plan. Count how many new contacts you need each month.
- Per user or per account. lemlist's Email plan includes unlimited users; Apollo bills every seat on the same plan; Reply.io's Email Volume bills per user on its smaller tiers and lists unlimited users on larger ones; Dripify bills per LinkedIn account, and Reply.io's LinkedIn add-on is per account too.
- Anti-spam law. In the US, the FTC's CAN-SPAM guide says business email needs honest subject lines, a postal address and a working opt-out. Other countries have stricter rules.
- LinkedIn's rules. LinkedIn publishes a help page on prohibited software and extensions. Read it before you connect any automation tool to your account.
Writing the emails is the other half of the job. Our best AI writing tools guide covers tools that help you draft copy, and AI automation tools can move new replies into your CRM.

FAQ
What is cold email software?
Cold email software sends personalized emails to people who haven’t heard from you before, in automatic sequences with follow-ups. Most tools also warm up your inboxes, rotate sending accounts and stop the sequence when someone replies, so you can reach more prospects without sending each email by hand.
Is cold email legal?
In the US, yes, if you follow the CAN-SPAM Act. The FTC says it applies to business-to-business email too: use honest sender details and subject lines, include a valid postal address and a way to opt out, and honor opt-outs within 10 business days. Other countries have stricter rules, such as GDPR in the EU. This isn’t legal advice; check the rules where your prospects live.
Is there free cold email software?
Apollo is the only one of these five with a free plan: on October 29, 2026 it gave 900 credits a year and 2 sequences, sending from Gmail accounts only. On October 15, 2026, lemlist and Reply.io offered 14-day free trials, Dripify a 7-day trial, and Instantly a free start with no card, without a stated length.
How many cold emails can I send a month?
It depends on the plan. Instantly’s Growth plan allows 5,000 emails a month, lemlist’s Email plan 50,000, and Reply.io limits active contacts rather than emails. Sending more than your inboxes can handle hurts deliverability, which is why these tools spread volume across several warmed-up accounts.
Which is cheaper, Instantly or lemlist?
On October 30, 2026, Instantly’s Outreach Growth plan was $47/mo ($37.60 yearly) for 5,000 emails, and lemlist’s Email plan $69/mo ($55 yearly) for 50,000 emails. Instantly is cheaper to start, but lemlist includes a lead database; with Instantly, lead data costs extra.
Is Apollo a cold email tool?
Partly. Apollo is a sales platform that combines a B2B contact database with email sequences, warmup and a dialer. On October 29, 2026, Basic cost $65 per seat a month ($49 billed yearly) with 30,000 credits per seat a year. Choose it if you need lead data and sending in one place; a dedicated sender like Instantly costs less if you already have a list.
Do I need a separate lead database?
Only if your sender doesn’t include one. Instantly’s Outreach plans don’t, so many teams pair a sender with a data tool. On October 29, 2026, Lusha’s Starter plan was $49.90/mo billed monthly (an email costs 1 credit, a phone number 5), and RocketReach Essentials was $49/mo or $329 a year, emails only. lemlist and Apollo include a database.
