The best way is usually to use a transactional email service rather than sending directly from your app or a personal mailbox.
Recommended approach
Use a provider like:
- Amazon SES
- SendGrid
- Mailgun
- Postmark
- SparkPost
These are built for account notifications like:
- password resets
- verification emails
- login alerts
- billing notices
- security updates
Why this is best
Transactional email services give you:
- better deliverability
- less chance of spam filtering
- bounce and complaint handling
- email delivery logs
- domain authentication support like SPF, DKIM, and DMARC
- scalability and reliability
Best practices
-
Send from your own domain
- Example:
no-reply@yourcompany.com - Avoid free email addresses like Gmail or Yahoo
- Example:
-
Authenticate your domain
- Set up SPF
- Set up DKIM
- Add DMARC
-
Use a separate subdomain for notifications
- Example:
notify.yourcompany.com - Helps protect your main domain reputation
- Example:
-
Keep emails concise and clear
- State the purpose immediately
- Include a clear call to action
-
Never hide critical account messages behind marketing systems
- Transactional emails should be separate from newsletters/promotions
-
Include security-friendly details
- For login alerts, mention time, device, and location if appropriate
- For password resets, make links short-lived and single-use
-
Make branding consistent
- Use your logo, company name, and support contact
- But keep it simple and readable
-
Avoid unnecessary attachments
- They can hurt deliverability and complicate security
If you want the simplest setup
For most teams:
- use Postmark or SendGrid if you want quick setup and good templates
- use Amazon SES if you want low cost and don’t mind more configuration
A good default architecture
- App triggers notification event
- Message queued in background job
- Email sent through transactional provider
- Logs and retries handled separately
- Unsubscribe not needed for truly transactional messages, but include support/contact info
If you want, I can also recommend the best provider for your stack or show a sample setup for Node, Python, or Rails.
