For password reset emails, the goal is usually maximum deliverability and trust, not marketing-style optimization.

What to use

  • A dedicated transactional sending domain or subdomain
    • Example: mail.yourdomain.com or notify.yourdomain.com
  • A separate IP or pool if you send enough volume
    • Keeps password resets isolated from marketing reputation
  • Strict SPF, DKIM, and DMARC
    • DKIM signing is especially important
    • DMARC should align with your visible From domain
  • A reputable transactional email provider
    • Common choices: Postmark, SendGrid, Amazon SES, Mailgun, SparkPost, MailerSend
  • Consistent From name/address
    • e.g. YourApp Security <security@yourdomain.com>
  • Clean, simple content
    • Avoid links besides the reset link
    • Avoid images, attachments, heavy HTML, and marketing language

Best practice setup

  • Use a dedicated subdomain for auth emails:
    • security@auth.yourdomain.com
  • Authenticate it with:
    • SPF
    • DKIM
    • DMARC
  • Warm up if you’re moving to a new domain/IP
  • Monitor:
    • bounce rates
    • complaints
    • inbox placement via seed tests if volume is high

My short recommendation

If you want the simplest, most reliable setup for password resets:

  • Use Postmark or Amazon SES
  • Send from a dedicated subdomain
  • Keep the messages purely transactional
  • Authenticate with SPF/DKIM/DMARC

If you want, I can also suggest the best provider by volume, budget, and setup complexity.
