From addresses

From addresses are the sender addresses your campaigns can send from. You manage them in Settings, under Sending, in the From addresses card below the sending domain. Each address is a local part, the text before the @, on your account's verified sending domain. When you compose a campaign, you pick one of these addresses in the Setup step.

The Sending settings page carries three cards: Sending domain, From addresses, and Quiet hours (which controls when journey emails are held back, covered in its own article).

Before you start: a verified domain

You cannot add a From address until your account has a verified sending domain. Every address lives on that one domain, so it has to exist and be verified first. The Sending domain card sits directly above the From addresses card on the same page; you set up and verify the domain in Account settings, and this page shows its status. Until a domain is verified, the From addresses card shows "No verified domain yet" with the prompt "Add and verify a sending domain above before adding From addresses."

Adding a From address

In the Add address form at the bottom of the card, fill in two fields and click Add address:

• From name (optional) is the display name that appears next to the address in the inbox. Up to 120 characters. Leaving it blank is allowed.
• Address is the local part you type before the @. Required, up to 64 characters, using only letters, numbers, and the characters . _ % + -. Your verified domain is shown fixed to the right of the field (for example @send.yourcompany.com), so you only type the part in front of it.

The local part is saved in lowercase. If you enter a character outside the allowed set, the form rejects it with "Use only letters, numbers, and . _ % + -"; an empty Address field returns "Enter the part before the @." A From name longer than 120 characters returns "From name is too long."

Only the local part is stored on the address; the full address is composed onto your domain when it is read or sent. If your verified domain changes later, every From address recomposes onto the new domain automatically, so an address is never left pointing at a stale domain.

The default address

One address is always the default, marked with a Default badge in the list. The first address you add becomes the default automatically. To change it, click Make default on the address you want; the badge moves to that address. The default is the address pre-selected when you start a new campaign, which you can still change per campaign.

If you remove the address that is currently the default, the oldest remaining address is promoted to default in its place, so the account is never left without one to pre-select.

Editing and removing addresses

Each address row has an edit (pencil) and a remove (trash) button. Editing lets you change both the local part and the From name, then click Save. The same validation applies as when adding: the local part is lowercased, capped at 64 characters, restricted to the allowed character set, and still has to be unique.

Clicking the remove button opens a confirmation dialog titled Remove this address?, which notes the address "will no longer be available to send from" and that "Campaigns already sent are unaffected." Removal is a soft delete: campaigns that already sent from the address keep their record, and the same local part can be added again afterward.

Choosing a From address in a campaign

In the campaign composer's Setup step, the From address dropdown lists your verified addresses. An address with a From name shows as Name <address>; without one, it shows the address alone. Picking an address also fills in its stored From name. A helper line reads "Campaigns send from your verified domain. Manage addresses in Settings → Sending."

If the account has no verified sender addresses, the Setup step shows "No verified sender addresses yet. Add one in Settings → Sending before sending this campaign." A campaign older than the managed list that still carries a free-text address shows it in the dropdown with an (unverified) suffix, so you can switch it to a managed one.

Journey emails use a different default

Journey emails do not use this list. A journey has no sender picker of its own, so it sends from the platform-level default sender address configured in Account settings' Sending domain card, a separate field from the From addresses managed here. Set that default before turning on a journey that sends email.
