Hosting mail is for correspondence. Campaigns need a different tool.
WHY NOT SEND FROM HOSTING
Hourly limits interrupt a campaign partway through No bounce handling, so invalid addresses keep being retried No unsubscribe management, which most jurisdictions require No delivery reporting One complaint-heavy campaign damages the sending reputation of every account on the server
WHAT TO USE INSTEAD
SendGrid, Brevo, Mailgun or a marketing platform. Most have free tiers adequate for a small list.
SETTING ONE UP
- Create an account and verify your domain.
- Add the SPF and DKIM records they supply, alongside your existing ones, in a single SPF record.
- Send from an address on your own domain.
- Import only addresses that opted in.
THE RULES THAT MATTER
Send only to people who asked. A list bought, scraped or collected from business cards is not a list you have permission to email. Include a working unsubscribe link and honour it promptly. Do not use misleading subject lines or From addresses.
Breaching these is both a policy problem and a reputation problem.
