Sending Domain

How sending works

SendBeam delivers your email through its own sending infrastructure. There are no API keys to create, no third-party accounts to connect and nothing to configure on the delivery side: every message is authenticated with DKIM and SPF for your domain, bounces and complaints are handled automatically, and the platform's guardrails protect your sending reputation.

What you control is which domain your email comes from and the from-name and address recipients see. Your monthly sending volume is set by your plan.

Start sending instantly

Every new workspace can send straight away from its own shared platform address, ws-<id>@mail.sendbeam.io, where the id is eight characters unique to the workspace (workspaces created earlier keep their yourworkspace@mail.sendbeam.io address). It is fully authenticated and fine for testing and for your first campaigns, and it is the only address on the shared domain the workspace can use. Most teams move to their own domain before sending to a real audience, because recipients recognise it and it builds reputation for your brand rather than the shared address.

Workspaces on the Free plan send from a shared address on mail2.sendbeam.io, a pool kept separate from paying customers so one plan's sending behaviour never affects the other's reputation. Workspaces on a paid plan use the main shared pool on mail.sendbeam.io, and verifying your own domain takes you off the shared pools altogether. The move between pools is automatic: when a workspace upgrades or downgrades, its shared address (the same ws-<id>@ local part) follows its plan on the next send, with nothing to change in your settings.

Add your own domain

1. Open Settings > Email & Domains and enter the domain you want to send from, for example yourbrand.com or a subdomain such as news.yourbrand.com.
2. SendBeam shows the CNAME records to add: DKIM signing records and a return-path record. Add them at your DNS provider (unproxied, if it offers proxying).
3. Once your DNS provider has enabled Domain Connect for SendBeam, the card also shows Connect with provider: you are taken to your provider, sign in there if you are not already, see the two records, and approve. SendBeam never receives a password or a token. Until a provider enables it the button is not shown, and adding the records yourself is the way.
4. SendBeam re-checks the records automatically about every minute; you can also click Verify. Verification usually completes within a few minutes, and the domain shows Verified when it is ready.

Choose your from-address

Once a domain is verified, pick the address on it that your email is sent from (hello@, news@, and so on) under the domain on the same page and click Set as default. The from-name is set in the Sender details section above it, where you can also send yourself a test email. Replies go to the from-address.

A workspace can send only as its own shared address or as an address on a domain this workspace has verified. SendBeam checks the from-address when you save it and again on every send, so an address on an unverified domain, or on a domain verified in a different workspace, is never used. The from-name is cleaned of line breaks, quotes and angle brackets and kept to 80 characters.

That is the whole setup. Next: add your first contact.
