We connect your system-generated email to any standards-compliant SMTP server — your own mail server, your hosting provider's, or a transactional email service.

SMTP is the plain, widely supported way to send email. It suits businesses that already have a mail provider they are happy with, or that send enough automated mail — password resets, notifications, invoices — to justify a dedicated sending service.

What we build with it

  • Invoice and document delivery
  • System notifications
  • Password reset and account email

How it works

  1. An event in the system produces an email — a document is shared or a user requests a password reset.
  2. The email is placed in an outbound queue rather than sent on the spot, so a slow mail server never holds up the user.
  3. A background process connects to your SMTP server over an encrypted connection and hands over the message.
  4. If sending fails, the message is retried, and persistent failures are logged for someone to look at.

Data exchanged

  • Recipient address
  • Message content
  • Attachments

What is needed to set it up

  • SMTP host, port and credentials
  • SPF, DKIM and DMARC records configured on your domain for deliverability

Good to know

  • Without SPF, DKIM and DMARC records, large mailbox providers are likely to send your mail to spam or reject it.
  • Transactional email services charge by volume, with rates set by the provider. Shared hosting mail servers often have low hourly limits.
  • Credentials are stored server-side and never exposed to the browser or mobile app.
