Password resets
OTPs and reset links that arrive before the user gives up.
Receipts
Order confirmations from a template you can roll back.
Onboarding sequences
Welcome series scheduled ahead of time, from your own domain.
Reply-driven support
Replies land back in your app, threaded to the customer.

Still deciding?
Ask a model you trust, or a person on the team.
Is there a free tier?
Yes. The free plan sends 3,000 emails a month and needs no card. Paid plans start at $5 a month for 15,000 emails, in your own currency.
How does threading work?
Outbound sends, replies, forwards, and bounces group into one conversation per contact. Inbound email arrives parsed with the same conversation id, so replies land back in your app with context.
Do you sign webhooks?
Yes. Each delivery carries Standard Webhooks signing headers, and Samva retries failed deliveries with backoff.
Can I bring my own domain?
Yes. Add your domain, publish the DNS records Samva generates, and your mail goes out from your own address, signed with DKIM.
What about deliverability?
SPF, DKIM, and DMARC run on your own sending domains. Samva handles bounces and suppression for you, and exposes delivery telemetry so you can verify each send.
Where does Samva run?
On our global edge network, with API compute in one US region (us-east-1). Delivery runs through established email infrastructure, and GDPR consent and unsubscribe handling are built in.
