Seamless.ai Pricing and Alternatives: What It Costs and Its Competitors
Seamless.ai is a B2B contact database. You search, it builds a list of emails and phone numbers in real time, and you spend credits to keep them. What it does not do is send the email, and that is the gap teams notice a few weeks in. A database hands you addresses; something else has to run the outreach. ColdMailer is that something else: it pulls and verifies LinkedIn leads, writes a personalized message for every prospect, and sends from inboxes you already own. Write a cold email below and see how it works.
Free to start. No credit card, no credit pool to burn down. Bring your own SMTP, with LinkedIn leads, AI writing, warmup, and follow-ups included.

What you get when you replace the database with a sender
Leads pulled from LinkedIn, not a credit pool
Filter by title, company size, industry, and geography and pull the contacts straight from LinkedIn. No annual credit package to run down, no export limit to negotiate.
Every address verified before send
Verification runs before the first email leaves, so bounces stay under the 2 percent line that keeps a domain healthy. A found contact is not the same thing as a deliverable one.
The AI writes each email
Every message is written for the individual prospect from their role, company, and context. A database gives you a name and an address; this gives you the email that actually gets a reply.
Bring your own SMTP
Send from Google Workspace, Microsoft 365, or any SMTP host you already pay for. Your domains, your sending reputation, under your control.
Warmup and follow-ups built in
Inbox warmup, multi-step sequences, and A/B testing come with Pro, so the whole outbound workflow lives in one tool instead of a database plus three others.
Published pricing, no sales call
Free to start, then $49 a month, listed on the page. No demo required to learn what the paid product costs.
ColdMailer vs Seamless.ai, honestly
These are not the same product, and any page that pretends otherwise is selling you something. Seamless.ai finds contact data in real time. ColdMailer sends cold email. The comparison worth making is what each one solves and what each one leaves you to solve yourself.
| Feature | ColdMailer | Seamless.ai |
|---|---|---|
| Published pricing | Free, $49/mo Pro, $149/mo Enterprise, listed publicly. | Free tier only. Pro and Enterprise require a sales quote. |
| What it does | Sends personalized cold email from your inboxes. | Builds lists of emails and phone numbers. No sending. |
| Contact data | Scraped and verified from LinkedIn, included. | Real-time search across the web, paid by credit. |
| Deliverability | Verification, warmup, and your own domain reputation. | Not its job. You still need a separate sender. |
| Billing | Monthly, cancel any time. | Annual credit packages, quoted per user. |
| Best fit | Teams that need to send, not just source, outreach. | Teams that already have a sender and only need data. |
If your only gap is data and you already run a sender you trust, Seamless.ai fills that gap. If you need to actually reach the people on the list, a database alone will not do it, and that is the case for ColdMailer.
Seamless.ai competitors compared
Most of these are contact databases; only ColdMailer sends the email. Buying the wrong half is the most common and most expensive mistake in this category. Every price below was read off the vendor's own public pricing page in July 2026, not copied from a roundup post.

Seamless.ai lists a free plan with 50 credits and shows no dollar figure for its Pro or Enterprise tiers, which require contacting sales. Hunter prices are in euros on its own page; do not convert them silently. Verify current pricing before you buy.

Connect your SMTP, let AI personalize every email, and start landing in the inbox. Your first 100 emails a month are free.
How to move from Seamless.ai to a full outbound workflow
Check what your credits actually bought
Pull last quarter's Seamless.ai usage. Most teams export far fewer contacts than their package covers, and the unused credits are the real price of the subscription.
Connect the inboxes you already own
Point ColdMailer at your Google Workspace or Microsoft 365 accounts over SMTP so your domains and reputation stay yours.
Pull and verify leads from LinkedIn
Filter by title, company, industry, and geography, pull the contacts, and let verification run before the first send so bounces stay low.
Let the AI write and send
Have the AI write a specific opener for each prospect, warm the inboxes, turn on follow-ups, and send. Data and sending in one place instead of two tools.
How much does Seamless.ai cost?
Seamless.ai publishes a price for one thing only: nothing. Checked in July 2026, its pricing page lists a free plan with 50 credits for a single user, and then two paid tiers, Pro and Enterprise, that show no dollar figure at all. Both ask you to contact sales, and both are sold as annual credit packages quoted per user. So the honest answer to what Seamless.ai costs is that the company does not say in public. Every number you find in a roundup post comes from a third party, a screenshot, or a leaked quote, not from Seamless.ai itself.
That is a deliberate choice, and it is worth reading for what it means rather than treating it as a mystery to solve. Credit-based, quote-only pricing lets a vendor set the number per account, which usually means the price scales with how badly they think you need it. For a buyer, the practical effect is that you cannot compare Seamless.ai against an alternative on price without booking a call first, and the free tier's 50 credits are enough to test the search but not to run a real campaign.
Why do people look for a Seamless.ai alternative?
Two reasons dominate. The first is the pricing model itself. Teams want to know what a tool costs before they invest a workflow in it, and a paid tier with no public price plus annual credit packages makes that impossible without a sales conversation. The second, and bigger, reason is that a database is only half of outbound. Seamless.ai is good at finding an email address and a cell number. It does not warm your inboxes, it does not write the email, and it does not send anything. You still have to buy or build the sending half separately.
That is where the real cost hides. A team signs up for the data, then discovers it needs a sender, a warmup tool, and a sequencer on top, and now outbound is four subscriptions instead of one. Consolidating the sending side into a single tool that also sources and verifies leads is usually why people go looking. If that is your situation, compare the category properly in our guide to B2B lead generation software before you commit to another annual data contract.
Is ColdMailer a replacement for Seamless.ai?
It replaces the reason most people buy Seamless.ai, which is getting verified contacts and then reaching them, without the part that trips teams up later. ColdMailer pulls leads from LinkedIn filtered by title, company, industry, and geography, verifies every address before the first send, writes a personalized email for each prospect, and sends from your own inboxes with warmup and follow-ups built in. That is sourcing plus sending in one place, where Seamless.ai is sourcing only.
Where the two genuinely differ is coverage of phone data. Seamless.ai leans hard on cell numbers for teams that cold call, and ColdMailer does not provide phone numbers because it is an email product. So if dialing is central to your motion, Seamless.ai covers something ColdMailer does not, and you might keep it for that. But if your outbound is email-first, ColdMailer covers the whole job at a published $49 a month instead of a quoted annual credit package. For the sending side specifically, our email outreach software overview lays out what a complete workflow looks like.
Who switches from Seamless.ai to ColdMailer
Founders who need to send, not just source
A list of emails does not book meetings. Start free, pull verified leads, and send personalized outreach from your own domain without buying a sender separately.
Teams tired of quote-only pricing
When the paid plan has no public number and renews annually, budgeting is guesswork. A published $49 a month is easier to defend and easier to leave.
Email-first outbound
If you rarely dial, you are paying for cell-number coverage you do not use. Buy the sender and skip the phone data.
Small teams consolidating tools
Data, verification, writing, warmup, and sequences in one tool beats stitching a database to three other subscriptions and reconciling the bill every month.
