Set up multiple senders on one domain

Why use multiple senders

You can create as many sender addresses as your team needs. There is a generous ceiling to prevent abuse — it counts every sender address across all the domains in your organisation, and it can be raised on request. Common uses:

• Per team — support@, sales@, and product@ all from the same domain, routing replies into different inboxes.
• Per product — if you run multiple products under one company, give each its own sender address.
• Per chat widget — every sender address is linked to one chat widget, and each brand has exactly one, so this decides which inbox a subscriber's reply lands in. Teammates with restricted access see those replies only if that brand is granted to them under Brand access on the Organization page.

All senders on the same domain share the domain's SPF and DKIM authentication — you don't need separate DNS records for each address. If the domain isn't verified yet, start with Verify your sending domain first.

Good to know: a sender stores only the email address and the chat widget it belongs to. There is no per-sender From-name, reply-to, default flag, or per-sender verification status — the From-name is set per campaign as free text, and verification status lives at the domain level.

Add a sender address on your custom domain

1. Go to Settings → Organization settings → Emailing → Custom Domains.
2. Select your verified domain in the domain dropdown. A green Verified badge appears next to the currently-selected domain — if it doesn't, complete domain verification first.
3. Open the Emails tab and click Add email.
4. Enter the local part of the address — the part before the @ sign. The domain suffix is fixed to your verified domain.
5. Pick the chat widget this sender belongs to. This is required — the form refuses to save without it. When a subscriber replies to a campaign sent from this address, the conversation lands in that chat widget's inbox.
6. Click Add.

The new address appears immediately in the sender dropdown when you build a campaign or configure an Email step inside an email automation.

Yaplet-hosted addresses are for conversations, not newsletters

You can also create a Yaplet-hosted address in the format [email protected] at Settings → Organization settings → Emailing → Yaplet Emails — click Create email address, enter a prefix of 3–30 characters (lowercase letters, numbers and . _ -, starting and ending with a letter or number; a small list of reserved prefixes is rejected), pick a chat widget, and click Create. These addresses are verified automatically, with no DNS setup.

They cannot be used to send newsletter campaigns. The sender dropdown in the campaign builder, in an automation's Email step and in the test-mail dialog lists only addresses on a verified custom domain. Yaplet-hosted addresses are for sending and receiving individual email conversations through your chat widget. To send a newsletter, verify a custom domain.

Remove a sender address

On a custom domain, click the delete icon next to the sender address you want to remove. On Yaplet-hosted addresses, hover the card to reveal the delete icon. Any campaign or email automation that referenced the deleted address will need to be updated before it can send.

What's next

With your senders in place, send your first campaign or build an automated email sequence to put them to use.
