Transactional Email

Transactional email is automatically triggered mail about a specific user action, such as a receipt or password reset, rather than promotional content.

अपडेट: अक्टूबर 6, 2026

Transactional email is a message sent one-to-one in response to something a user did or something that happened to their account: order confirmations, password resets, login codes, invoices and security alerts.

Why it matters

Recipients expect these immediately, so delays or spam placement directly hurt the product; a missing reset email can mean a lost customer. Because they are triggered and wanted, they generally enjoy higher engagement than marketing mail. Many teams send them through a separate subdomain or provider stream from bulk email, so a marketing complaint spike cannot hurt critical mail. They still need SPF, DKIM और DMARC alignment. Adding promotions to them may change how laws treat them.

Example

A password reset flow:

From: Example <no-reply@mail.example.com>
Subject: Reset your password
Body: Use this link within 30 minutes: https://example.com/reset?t=...

Sent from mail.example.com, which has its own DKIM key and reputation separate from news.example.com used for newsletters.

Common mistakes

  • Mixing marketing and critical mail on one IP and domain.
  • Using no-reply addresses that cannot receive replies about problems.
  • Not monitoring delays, which for greylisted first mail can break one-time codes (see greylisting).
