ChangelogA help centre, and someone to ask

A help centre, and someone to ask

There is now a proper help centre at help.mails.ai: six sections and twenty-two articles covering the first send, the send path, inbound events and webhooks, custom domains, the deliverability policy, and keys and billing.

ChangelogFewer decisions before your first send

Fewer decisions before your first send

Setup opened with an empty field, a disabled button, four validation rules and the warning that the name is permanent — an irreversible naming decision demanded of someone who arrived twenty seconds ago and has not yet seen the product do anything.

ChangelogA second way in

A second way in

The only route into the product had no fallback: one delivery path having a bad day meant nobody could sign in.

Disagree with a refusal

ChangelogA refusal that tells you what to change

A refusal that tells you what to change

422 cold_email_prohibited used to end with "if you believe this is transactional, contact support" — which tells a developer nothing they can act on, and turns a ten-second edit into a support thread they will never open.

ChangelogDelivery, actually confirmed

Delivery, actually confirmed

A message used to sit at sent forever on the default rail, because the send response could never confirm anything.

ChangelogSend from your own domain

Send from your own domain

On a paid plan, add a domain, publish the DKIM record we hand back at your own registrar, verify, and the agents you create on it send as agent@yourcompany.com — DKIM-signed with a key generated for your domain alone.
