Overview

Email deliverability is the ability of your emails to successfully reach your recipients' inboxes. A well-configured email account, clean recipient list, verified sending domain, and good sending practices all contribute to higher delivery rates and better campaign performance.

SPRL provides tools such as Email Validation, Sender Mailing, Domain Configuration, Suppression Management, and campaign analytics to help improve email deliverability.

Factors That Affect Deliverability

Use a Business Email Address

Always send campaigns using a business email address associated with your own domain.

Free webmail providers such as Gmail, Yahoo, Outlook.com, AOL, and Hotmail should not be used as sender email addresses. Using a business domain improves sender credibility and helps receiving mail servers recognise your organisation.

Verify Your Sending Domain

Configuring your sending domain helps establish your domain as an authorised sender and improves email authentication.

Ensure your domain is configured correctly before sending large email campaigns.

Validate Your Recipient List

Before importing contacts, validate your email list using the Email Validation module.

Only import recipients with an "OK" verification status. Sending emails to invalid or inactive addresses increases bounce rates and can negatively affect your sender reputation.

Maintain Clean Recipient Groups

• Remove outdated email addresses.
• Delete duplicate recipients.
• Import only validated email addresses.
• Organise recipients into appropriate Recipient Groups.
• Update recipient lists regularly.

Monitor Campaign Performance

Review campaign analytics after every campaign to identify delivery issues early.

Pay particular attention to:

• Delivery Rate
• Bounce Rate
• Suppressed Recipients
• Unsubscribers

Investigating these metrics regularly helps maintain healthy mailing lists and improves future campaign performance.

Respect Recipient Preferences

Always include an unsubscribe link in marketing emails. Removing recipients who no longer wish to receive your emails helps maintain engagement and improves sender reputation.

Avoid These Common Mistakes

• Using free email addresses as the sender.
• Sending emails to unverified recipient lists.
• Ignoring high bounce rates.
• Continuing to send to suppressed recipients.
• Sending campaigns without reviewing previous analytics.
• Using outdated mailing lists.

Best Practices

• Verify your sender email address.
• Configure and maintain your sending domain.
• Validate recipient lists before every major campaign.
• Use Recipient Groups to organise contacts.
• Review campaign analytics regularly.
• Keep suppression lists up to date.
• Send test emails before launching large campaigns.

Troubleshooting

Why are my emails bouncing?

Bounce rates usually increase when invalid, inactive, or incorrectly formatted email addresses are included in your recipient list. Validate your email list before sending.

Why should I use my own business domain?

Business domains help improve sender trust and increase the likelihood of successful email delivery.

Why are some recipients suppressed?

Suppressed recipients are automatically excluded to help protect sender reputation and reduce repeated delivery failures.

How often should I validate my email list?

Validate your mailing list regularly, especially before large campaigns or when importing new contacts.
