Keeping your contact data clean

Accurate contact data is the foundation of successful delivery. Here's how to maintain it.

Step 1: Add Contacts Carefully

• Include correct reference numbers and email addresses

• Use consistent formatting

• Avoid duplication

Tip: Upload via SFTP in batches or use the Contacts > Add Contact tool for one-offs.

Step 2: Review Failures Regularly

Undeliverables often point to:

• Typos in reference numbers

• Missing or invalid email addresses

• Subscription expiry

Fix the contact record and resend mail as needed.

Step 3: Use Validations

Ask your Payreq account manager or customer support team to enable validations during uploads—e.g. check for known contact reference formats or enforce length rules.

Step 4: Remove or Archive Inactive Contacts

We recommend reviewing and archiving old or inactive records quarterly to keep things tidy.
