Mails.now Review: Cheap Cold Email Tooling With a Big Catch

Say you’ve got a list of a few thousand prospects and a plan to email them from several domains, so no single address takes all the heat. Setting that up normally means buying domains, adding DNS records, creating mailboxes one at a time, and then paying for a separate tool to run the sequences. It’s tedious, and it adds up.

Mails.now is trying to put all of that in one place. The pitch on AppSumo is mailbox and domain provisioning, a multi-sender sequencer, analytics, and a transactional email API, all reachable through a REST API. It’s aimed at developers, marketing agencies and SaaS teams, according to the listing. That’s a narrower crowd than the Mailchimp and ActiveCampaign comparisons suggest.

What you actually get for $49

The entry tier is $49, down from a listed $299. Higher tiers run $98, $147 and $196, each with a bigger list price crossed out. Every tier is a lifetime deal, includes all future plan updates, and lets you stack up to 4 codes. You have to redeem within 60 days of purchase.

The core is a mailbox and domain API. You can provision domains, verify DNS, and create single or bulk mailboxes from the dashboard or by API. The listing says every inbox is sequencer-ready from day one, which is the useful part. You’re not wiring each new mailbox into a separate sending tool.

The second piece is the sequencer. You import leads by CSV, organise them with static lists and colored tags, and enroll a whole audience in a campaign with one click. Multi-sender rotation spreads the sending across your mailboxes. That’s standard for outbound tools, and the listing doesn’t describe the rotation rules, so we can’t say how much control you get.

Tracking and the API side

Analytics cover opens, clicks, replies and bounces, broken out by mailbox, step and domain. Per-mailbox and per-domain numbers matter if you run several domains. They show which one is dragging your results down. The listing doesn’t show any dashboards, though, so we can’t judge how readable they are.

This is where the product looks most developer-minded. Besides REST endpoints for mailboxes, sequencer campaigns and transactional sends, there are webhooks for events like email.received, sequencer.email.sent and sequencer.lead.replied. The listing also mentions MCP tools, which suggests you could drive it from an AI assistant. If you build internal tools, that’s a real selling point. If you don’t write code, it’s mostly irrelevant to you.

Transactional email runs on the same infrastructure. That means order confirmations, password resets and notifications can go through the same account as your campaigns. Mixing them is a choice to think about carefully, since a bad outbound campaign can hurt the reputation of whatever sends your password resets. The listing doesn’t say whether you can separate the two.

The catch: there is no SMTP

Here’s the line in the listing that matters most. Mails.now doesn’t provide its own SMTP. You must connect your own relay, such as Amazon SES, Mailgun, Postmark, Google Workspace, Gmail or Microsoft 365.

So this isn’t an all-in-one sender. It’s a control layer on top of sending you pay for elsewhere. If you already run Google Workspace seats or an SES account, that’s fine. If you were hoping $49 would cover everything, it won’t.

The setup FAQ points the same way. It tells you to find where your DNS is managed, get your SPF, DKIM and DMARC records from your SMTP provider, and add them yourself. There’s a Domain Info feature to help you spot your domain host. Fair enough, but it means you need to be comfortable with DNS.

The listing is also unclear on how the mailbox creation fits with the no-SMTP rule. If mailboxes are created through your own provider, it doesn’t explain what Mails.now does at that step. Ask the team before you buy.

The limits at each tier

The listing gives the plan numbers as a row of four values, such as 40 / 30 / 20 / 10 sender domains, but never labels which value belongs to which tier. Since the tiers are listed from $49 to $196 and the numbers fall from left to right, it looks like the first value is tier 4 and the last is tier 1. That’s our reading, not something the listing states. Confirm it on the checkout page.

On that reading, the $49 tier gives you:

• 10 sender domains
• 20 mailboxes
• 5,000 total leads
• 100,000 one-time email send credits
• 3,000 transactional emails per month

The $196 tier gives 40 domains, 80 mailboxes, 20,000 leads, 400,000 credits and 9,000 transactional emails per month. The scaling is roughly linear, so you aren’t getting a volume discount by paying more.

The word to watch is one-time. Those send credits don’t renew each month. At 100,000 on the entry tier, a 5,000-lead list with a four-step sequence would use up about 20,000 sends. That’s workable for a while, but it’s a finite pool. The listing doesn’t say what happens when it runs out or whether you can buy more.

Also keep in mind that 20 mailboxes sending cold outreach still depend on your domain reputation and your provider’s rules. Credits are a cap on volume, not a promise of inbox placement. The listing says nothing about deliverability, warm-up or spam testing.

Who should skip it

Skip it if you want to send newsletters to a customer list. There’s no template builder, form, or landing page described, and the Mailchimp comparison is a stretch. This is an outbound sequencer with an API.

Skip it if you don’t want to manage DNS and an SMTP provider. And skip it if you need proof the product will be around in five years. The listing gives no company history, customer count or roadmap, and a lifetime deal is only as good as the team behind it.

It does make sense for a developer or small agency that already has a sending provider and wants an API-first sequencer. The $49 entry point is low enough to try, and the 60-day redemption window gives you some time to check the setup. Just confirm the DNS and SMTP details before you commit.
