Professional email depends on more than mailbox storage. DNS alignment, authentication, backups, and a clear migration plan all matter to deliverability and trust.
The essentials to verify
- Publish SPF, DKIM, and DMARC records for the sending domain.
- Set mailbox limits and aliases around how your team actually works.
- Document migration timing, credentials, and DNS cutover steps before moving users.
A good email platform should make these controls understandable and keep the daily experience simple for the people who use it.
