Use an email testing/staging mailbox or email-sink tool, not a real inbox.
If your goal is to see every email your app attempted to send, common options are:
- Mailtrap — captures outgoing email in a safe inbox for testing
- MailHog — local development SMTP server with a web UI
- Mailpit — similar to MailHog, modern and easy to use
- SMTP logging / provider event webhooks — if you want to track sends in production
Best choice depends on your environment:
- Local development: MailHog or Mailpit
- Team/shared testing: Mailtrap
- Production tracking: email provider logs, bounce/delivery webhooks, or an app-level outbox table
Important distinction
If you mean “attempted to send” rather than “actually delivered,” you should also:
- log email send requests in your app
- store message IDs / provider response IDs
- capture failures and retries
- use provider webhooks for delivery/bounce events
If you tell me your stack (e.g. Node, Rails, Django, .NET) and whether this is local, staging, or production, I can recommend the best exact setup.
