Deliverability changelog

• The emails list in Email API → Emails has a Spam score column. Sort by it, or show and hide it in Display options.
• Score badges are green below 5, orange from 5 up to 7, and red at 7 or more, the score at which Emailit holds a message. Gray means the message wasn’t inspected.
• On the email detail page, each delivery row shows its status, the full reason and the time on one line.

See Spam checks.

Emailit compares the addresses in Reply-To and From, ignoring display names and letter case. When they’re the same, it removes Reply-To before signing the message. Replies still reach the From address.

When the addresses differ, Reply-To is kept unchanged. See Email headers.

Open an email in Email API → Emails to find the Spam Checks panel under the deliveries. It lists every rule the spam filter matched, with a description and a score. Filter by Negative (rules that raised the score), Positive (rules that lowered it) or Neutral.

Messages that score 7 or more are held. Use the checks to find what to change, then retry the email. See Spam checks.

Emailit raises the per-second and daily sending limits of healthy Pro and Business workspaces automatically, at most once every 7 days.

On Pay as you go, your limits stay the same until you ask for more with Request Increase on the dashboard’s Sending Limits card. See Limits.

Emailit calculates sending health every hour from the bounce rate among unique recipients over the last 7, 30 and 90 days, once you’ve sent to at least 100 unique recipients. You’ll find it in three places:

• Dashboard: the workspace score and status.
• Analytics: bounce rate and complaint rate charts.
• Domain → Sending health: the score and its history by day, week or month for one domain, on Pro and above.

Keep your bounce rate under 2% to stay healthy. Above 4%, the workspace is at risk. See Sending health.

Before delivery, Emailit checks each signed message with Rspamd, an open-source spam filter. Messages that score 7 or more get the status held instead of being sent, so mail that would likely land in spam doesn’t hurt your reputation. If the spam filter is unavailable, mail is sent without a score rather than delayed.

To release a held message, fix its content and retry it. See Spam checks.

When a recipient marks your email as spam and their provider reports it through a feedback loop, Emailit matches the report to the original email, sets its status to complained and sends an email.complained event. The address is added to your suppression list as a complaint, so you don’t email it again.

See Bounces and complaints.

• Bounce messages that arrive after delivery are matched to the original email, which is then marked bounced.
• Over-quota, unknown-user and disabled-mailbox replies sent with temporary 4xx codes are treated as hard bounces instead of being retried.
• After a 451 reply, Emailit pauses delivery from that IP to that recipient domain for 5 minutes, and for 1 hour after a 550 5.7.1 block.

See Bounce categories.
