Sender addresses are the identities your emails are sent from. Every campaign and automation email picks one of your verified senders.

​
From address vs. reply-to

  • From address — what recipients see as the sender (Maya from Acme <maya@acmestore.com>). It should be on your verified sending domain.
  • Reply-to address — where replies go, if different from the from address. Useful when you send from hello@ but want replies in your support inbox.

​
Add a sender address

1

Create it

Go to Settings → Email → From Addresses and click Add address. Enter the email and the from name customers will see.
2

Verify it

Retainful sends a verification email to that address. Click the link inside. Only verified addresses can be used in campaigns and automations.
Reply-to addresses are managed the same way under Settings → Email → Reply Addresses.

​
Choosing a good from name

The from name is the most visible thing in the inbox — often more than the subject line.
  • “Maya from Acme” — personal and branded; a strong default.
  • “Acme” — clean and recognizable.
  • Avoid “noreply@…” — it tells customers you don’t want to hear from them, and replies are a positive deliverability signal you’d be giving up.
Don’t send from a free mailbox domain like @gmail.com. DMARC policies on those domains cause your messages to fail authentication when sent through any email platform. Always use an address on your own domain.

​
Blocked domains

Under Settings → Email → Blocked Domains you can maintain a list of recipient domains Retainful should never send to — useful for blocking known spam-trap domains or a partner’s domain that asked to be excluded.
