Everything you need to send

Personalized Campaigns

You want every email to feel one-to-one… but hand-editing names, companies, and details for thousands of recipients simply isn't possible.

Now merge tags like {{name}} and your own custom fields fill in per recipient — with fallbacks — across subjects, bodies, and saved templates.

Every recipient gets their own details, automatically.

Hi {{name}} — your June updates are here. Take an early look at everything we shipped this month.

Import & Groups

Your contacts are scattered across spreadsheets… but importing them, clearing duplicates, and keeping groups tidy eats hours you don't have.

Now a CSV or Excel import validates and de-duplicates every contact, and a group column files each one into the right group on the way in.

Import thousands of contacts in a single drop.

Deliverability & Reputation

One bad send can wreck your sender score… but catching bounces, complaints, and risky addresses by hand is a losing battle every campaign.

Now bounces and complaints are auto-suppressed, risky addresses are flagged before you send, and every open and click is tracked for you.

Bounces and complaints suppressed automatically.

Built for Developers

Your sending should plug into everything else… but wiring up an email service and reacting to its events usually means glue code and headaches.

Now a clean REST API and signed webhooks let you send, manage contacts, and react to every open, click, and bounce as it happens.

REST API, webhooks, and an SDK out of the box.

Your Own Domain

You want mail to come from you, not a shared service… but DNS and email authentication are fiddly, and getting them wrong means the spam folder.

Now add a domain and we generate the exact SPF, DKIM, and DMARC records to publish — verified automatically, then send from any address on it.

Publish three DNS records and you're verified.

Frequently asked questions

Still confused?

Can't find the answer you're looking for? Our team is happy to help you out.

Contact us
Do I need my own domain to send?

You can start sending right away on our shared infrastructure. To send from your own address, add a domain and publish the SPF, DKIM, and DMARC records we generate — we verify it automatically.

How does pricing work?

Start free, no card required. Paid plans scale with the volume you send and unlock more domains and team members — upgrade, downgrade, or cancel anytime.

Can I import my existing contacts?

Yes. Drop in a CSV or Excel file and we validate and de-duplicate every contact on the way in, filing each one into the right group automatically.

How do you keep my emails out of spam?

Bounces and complaints are suppressed automatically, risky addresses are flagged before you send, and every open and click is tracked so you can protect your sender reputation.

Is there an API for developers?

A clean REST API, signed webhooks, and an MCP server let you send mail, manage contacts, and react to every open, click, and bounce from your own stack.
