# Sender addresses

> Set up verified from and reply-to addresses for your campaigns and automations.

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](/email-setup/sending-domains).
* **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

<Steps>
  <Step title="Create it">
    Go to **Settings → Email → From Addresses** and click **Add address**. Enter the email and the **from name** customers will see.
  </Step>

  <Step title="Verify it">
    Retainful sends a verification email to that address. Click the link inside. Only verified addresses can be used in campaigns and automations.
  </Step>
</Steps>

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.

<Warning>
  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.
</Warning>

## 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.
