What are the best practices for sending bulk email?
You should use these best practices when you send bulk mail from/to HostMarlin Mail customers:
- Send only to recipients who explicitly subscribed to your emails (not list purchases, list rentals, or email appends).
- Offer an unsubscribe link, so that the recipient can unsubscribe immediately.
- Ensure emails are compliant with RFC 5322.
- Publish reverse DNS with your domain to help identify your IP addresses.
- Use consistent sending IP addresses and domains for your bulk email, but do segment marketing and transactional email streams.
- Use a consistent From: name and address to clearly identify your brand.
- Make use of Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate your emails.
- Track the temporary and permanent SMTP errors from our mail servers and act on them accordingly.
- Have a standard policy for handling bouncing addresses.
- Periodically remove inactive subscribers from your list.
- Don't reactivate email addresses that are already on your unsubscribe or suppression list.
