SPF, DKIM and DMARC - basics of mail deliverability

When this matters

Without these records, messages more easily go to spam and domain spoofing is harder to detect.

How SPF, DKIM and DMARC protect domain mail: server authorization, message signatures, domain policy and reports.

Practical checklist

• add SPF with authorized servers
• enable DKIM for mailboxes
• start DMARC carefully
• check reports and recipient replies

What to prepare before contacting support

If you need support, include the domain, account name, time of the problem, exact error message, recent changes and one example URL or mailbox. This lets support check DNS, SSL, mail logs, PHP, database, backups and application configuration faster.
