Getting started

What is Pombo?
An email platform where the software does the drafting. You describe an outcome, and Pombo writes the campaign, plans the sends, and reports on what worked, in your brand voice. It also runs from an AI agent like Claude or ChatGPT.
Do I need technical skills to use it?
No. Building campaigns, sequences, and templates is all visual, and you can ask the AI to make changes in plain language. The API and agent integration are there if you want them, not required.
How is Pombo different from Mailchimp or a traditional ESP?
A traditional tool gives you a blank editor. Pombo starts from your goal and drafts the whole thing, then keeps it on brand across every send. And every part of it, including migrating your account in, can be done by an AI agent.
How long does setup take?
About 15 minutes, most of it waiting on DNS to verify your sending domain. See the quickstart.

Sending and deliverability

Why can't I send yet?
New accounts clear four gates first: account approval, a permission attestation, a verified sending domain, and the weekly send cap. A blocked send tells you which gate stopped it. Full detail in sending gates and the waitlist.
Do I need my own domain?
Yes. Pombo will not send from a domain it can't authenticate with DKIM, SPF, and DMARC. Use a dedicated sending subdomain like mail.yourcompany.com. Check yours with the free email authentication checker.
Is sending really unlimited on paid plans?
Yes. Every paid plan has no send cap. The free plan is limited to 1,000 emails per week and 1,000 contacts. Pricing is by contact count, not volume.
Does Pombo handle bounces and unsubscribes automatically?
Yes. Hard bounces and spam complaints are suppressed permanently, and unsubscribes are honored across every send. You never scrub a list by hand. Re-importing a suppressed address does not un-suppress it.

AI

Does the AI send emails without my approval?
No. Everything the AI generates, whether in the app or through a connected agent, is a draft. Nothing sends until you review it, and every agent action is logged.
Can it write in my brand's voice?
Yes. Set a brand voice profile once and every generated email, subject line, and sequence follows it instead of sounding like generic AI.
Is my data used to train AI models?
No. Your contacts and content are not used to train models. Generation runs against your data at request time to produce drafts for you, and that's it.

Migrating

Can you move me off my current tool?
Yes. A connected AI agent can migrate the account: contacts, custom fields, templates, and sequences. Most teams are sending within a day. See migrating from another platform.
Do my unsubscribes come across?
Yes, if you include them. Export the people who opted out of your old tool and import them with an unsubscribed status. They stay in your audience but are never emailed.
Will my templates survive the move?
Yes. HTML and MJML come across as-is through the raw code import, so existing designs render exactly as before. The agent can also rebuild them as editable blocks.

Pricing and plans

How does pricing work?
By the number of subscribed contacts you have. Unsubscribes are free. Every plan includes every feature; the tiers differ only on contact count and support. See pricing.
Is there a free trial? Do I need a card?
There's a free plan, not a trial. No time limit and no card. It covers 1,000 contacts and 1,000 emails a week, with the full platform. Paid plans lift both limits.
Can I stay on the free plan forever?
Yes. It doesn't expire. Upgrade when you outgrow 1,000 contacts or need more than 1,000 sends a week.
Can I change plans later?
Yes, up or down, from Settings. Billing is monthly and you can cancel any time.
Do unsubscribed contacts count toward my plan?
No. Unsubscribes are free. Only subscribed contacts count toward your plan, so unsubscribed, bounced and undeliverable contacts cost you nothing. Keep them: they stay in your audience so you never accidentally email them again, which deleting them would lose.

Developers and security

Is there an API?
Yes. A REST API for firing lifecycle events, sending transactional email, and keeping contacts in sync. See the API reference.
Can I connect Claude or another AI agent?
Yes. Pombo runs an MCP server. Add it as a remote server in Claude, Cursor, or any MCP client and sign in with OAuth. See connecting an AI agent.
Where is my data stored?
In the United States, on AWS. Transport is encrypted, and we support data export and deletion requests. See the privacy policy.
