Know why an email did or didn't land.
Your mail goes out from your own domain with SPF and DKIM set up for you. Bounces and complaints are suppressed automatically, and every send has events you can check, so an email never just disappears into the void.
- DOMAINacme.co, one rack per domain
- RECORDSDKIM and SPF generated, DMARC checked
- STATUSrecords verified
Your domain, set up in three records.
| Record | Host | What it does |
|---|---|---|
| TXT | samva-<id>._domainkey.<yourdomain> | DKIM: signs your mail so receivers can check it came from you. |
| MX | mail.<yourdomain> | Custom return path: where bounces come back to. |
| TXT | mail.<yourdomain> | SPF: authorizes Samva to send for the return path, so SPF aligns with your domain. |
| MX | <yourdomain> | Routes replies to your app. Only when receiving is on. |
- If Cloudflare or Vercel hosts your DNS, connect it and the records are added for you.
- DMARC is your policy. Samva shows what you publish and links the guide, and never creates the record.
What Samva does for you.
Dead addresses stop getting mail
A hard bounce or a complaint suppresses the address. List suppressions, and lift one once the address is fixed.
Your own reputation
Each account sends with its own reputation, so another customer's list cannot drag yours down.
Warm up a new domain
Warm-up paces campaign sends on a new domain. Transactional email is never delayed.
Clear limits, published
Sending pauses if, over 24 hours, complaints pass 0.1% or hard bounces pass 5%, once you have sent at least 200 emails.
Your tracking domain
Track opens and clicks on your own domain, on the Growth and Scale plans.

Common questions.
Which DNS records do I publish?
a TXT record at samva-<id>._domainkey.yourdomain.com; an MX record at mail.yourdomain.com; a TXT record at mail.yourdomain.com; and an MX record at yourdomain.com, only if receiving is on. Samva shows the exact names and values in the dashboard. If Cloudflare or Vercel hosts your DNS, connect it and they are added for you.
Does Samva set up DMARC?
No. DMARC is the policy you set for your domain. Samva shows the policy it finds and links a guide to setting one.
What happens when an email bounces?
A hard bounce or a complaint suppresses the address until you lift it. A soft bounce suppresses it for 30 days.
How long does verification take?
Often minutes, sometimes a few hours while DNS propagates.
Do new accounts have limits?
New accounts send on probation with tighter thresholds, and some are reviewed before their first send.
