Deliverability and domain warm-up

The Deliverability page (a top-level Deliverability entry in the sidebar) shows the health of every sending domain in your workspace on one screen, on its Domains tab. Its Bounces tab holds bounce management: see Email analytics. The same checks run before a campaign sends, so a problem you can see here is a problem that can hold up a send.

What the page shows

Each domain you’ve added under Settings → Domain Authentication gets a row. Click a row for details: messages sent, Delivered, Bounced and Complaints counts, DMARC coverage, and any DNS drift. The header shows the reporting window (by default the last 30 days).

Reputation thresholds

Reputation is judged per domain, per day: The At risk limits match the levels at which Amazon SES starts an account review, and Watch warns you before you get there.

All clients at once

If you run email for several clients and their workspaces belong to an organization, the All clients tab opens the organization’s Deliverability tab: every sending domain across every workspace attached to the organization, on one page. You see which client’s DKIM record drifted or which domain was listed without switching workspaces. The tab appears when the workspace you are in belongs to an organization you are a member of. All your clients’ domains appear in one list, sorted worst first: at-risk domains at the top, then blocklisted ones, drifted DNS, domains on Watch, domains with a check that has never run, and healthy domains last. The columns are the ones on the Domains tab plus a few more: Client, the workspace the domain belongs to; the published DMARC policy (p=none is monitoring only, so it is flagged) next to DMARC alignment; Brand mark, how many of the five brand mark steps the domain has done; and Sent in window, how many emails the domain sent in the period you picked. The same rule applies as on the Domains tab: a signal nobody has checked yet shows as unknown, never as clear. Filter by workspace or search for a domain to narrow the list. The totals at the top add up domains, drifted records, blocklist listings, at-risk domains and unchecked domains across all your clients. Every domain row has an Open button that switches you to that domain’s workspace, so you can fix the problem there. Every organization member can see the tab. Suspended workspaces don’t appear; a note above the table says how many were left out.

Refreshing the checks

Owners and administrators see three buttons at the top of the page:

• Check DNS re-reads every domain’s published records and updates drift.
• Sweep blocklists re-checks every domain against the blocklists.
• Recompute reputation recalculates the reputation snapshot from recent sends.

A grey banner tells you when some domains have never been checked or swept. Unchecked is not the same as clean, so run the checks after you add a domain.

When a domain blocks sending

A red banner at the top lists how many domain issues will block sending, broken down into DNS drift, blocklist listings and at-risk reputation. Before a campaign sends, its sender’s domain goes through these checks: Fix the cause, run the matching check again, and the block clears.

Domain warm-up

A new domain that jumps from zero to thousands of emails a day gets filtered, because mailbox providers want to see volume grow gradually. A warm-up ramp sets a daily sending cap that grows every day. How the ramp works

• The cap starts at 50 emails on day 1 and doubles each day until it reaches your target. The last day is the target itself. A ramp never lasts more than 60 days.
• Days follow the UTC calendar: a new day starts at 00:00 UTC whether or not you sent anything. When the last day passes, the ramp is complete and the cap is lifted.
• Campaigns and journeys sending from the domain count toward the same daily cap.

What happens when today’s cap runs out

• Campaigns send as many recipients as today’s cap allows. The rest of the send is parked and continues automatically at 00:00 UTC. The campaign page shows a note like “Warm-up: day 2 cap of 100 reached — the rest continues at 00:00 UTC”.
• Journeys send one email at a time. Once the cap is spent, further journey emails from that domain are held until the next UTC day.

Pausing and ending

• Pause warm-up stops all sending from the domain. The pre-send check blocks while a ramp is paused.
• Resume warm-up continues at today’s day on the calendar, not the day you paused. Days keep counting while a ramp is paused.
• End warm-up finishes the ramp early and removes the cap.

Brand mark: your logo in the inbox

Gmail, Yahoo and Apple Mail can show your logo next to your emails. Open a domain’s row on the Deliverability page to see its Brand mark card. The card walks you through five steps and shows whether each one is done, needs attention or is still to do, with the exact DNS record to publish and a copy button. Click Run check after each change to read your DNS, logo and certificate again. Owners, administrators and anyone else with permission to change settings can run the check and edit the card.
