Why Email Deliverability Is a Challenge

On shared hosting, many domains share the same outbound IP address. If one customer sends spam, it can affect the reputation of that IP and impact everyone using it.

Essential DNS Records for Email

• SPF: Defines which servers can send mail for your domain.
• DKIM: Cryptographically signs messages to prove authenticity.
• DMARC: Instructs providers how to handle messages that fail checks.

Best Practices for Sending

• Avoid sending bulk promotional emails from shared hosting.
• Use double opt in for newsletter signups.
• Keep lists clean by regularly removing inactive addresses.

When to Use a Dedicated Email Service

If email is critical for your business, consider moving outbound mail to a specialist provider. They focus exclusively on deliverability, reputation and compliance so your messages reach inboxes more reliably.
