TODOS

- [x] Fix translation of Markdown files
- [x] Log in as seems to hang (in admin)

- [x] `HEAD /` (e.g. support UptimeRobot)
- [x] Too many DNS lookups (SPF cap of 10 should be increased to 20 maybe)
- [ ] "Leave us a review on G2 https://www.g2.com/categories/other-email Trust Pilot https://www.capterra.com/p/166646/SMTP2GO/ and capterra https://www.trustpilot.com/review/www.smtp2go.com" (in footer of emails)
- [ ] `rg "TODO"` in codebase
- [ ] Slack notifications with errors (anonymous data/omit fields)
- [x] When account is upgraded, verification error message should appear
- [ ] if > 10 on the recipients list for an alias or catch-all, then add List-Unsubscribe and Feedback-ID header information

This issue is a broad, mixed TODO list rather than a scoped change. Start by selecting one unchecked item, such as the POST alias creation request or the DNS and email-header work, then locate its relevant entry point and tests; done should be defined in a separate, focused issue.
