An AI app builder whose apps send real email

Describe the app and Mortar builds it in real Django — and when it needs to email your users (sign-ups, password resets, receipts), a dedicated email server sends from your own domain, isolated from every other project.

How email works

  • ✓A dedicated, reputation-isolated email server per project — one flat subscription, transactional sends included; no other customer's sending can hurt your deliverability.
  • ✓Send from your own domain: DKIM verification is guided, and domains bought through Mortar are configured automatically — nothing to copy-paste.
  • ✓Every project gets its own sending identity even without a custom domain — never a shared from-address.
  • ✓Deliverability protection built in: per-project isolation plus automatic pause on bounce/complaint spikes.
  • ✓Prefer your own provider? Bring your own SMTP (Gmail, SendGrid, Mailgun, anything that speaks SMTP) with your keys instead.
  • ✓Real Django (Python) — models, views, templates, migrations, tests.

Frequently asked

Can my app send email from my own domain?
Yes. Verify your domain with a couple of DNS records (shown in the dashboard) — and if you bought the domain through Mortar, the records are added for you automatically. Your app then sends as any address on that domain.
What kind of email can my app send?
Transactional email your app triggers — sign-up confirmations, password resets, order and booking confirmations, receipts. It is not a bulk-marketing tool.
Do I own the code Mortar generates?
Yes. Every project is a real Django repository you can export in full and run anywhere — there is no proprietary runtime and no vendor lock-in.
