Email Validation - Best Practices

Email Validation Best Practices

Email validation is most powerful when used intentionally and consistently. Below are best practices to help you get the most out of this feature and ensure your contact lists stay clean and campaign-ready.


🗓️ When to Run Email Validation

  • Before Major Email Campaigns
    Clean your list before newsletters, event invites, or product announcements to reduce bounce rates and improve performance.

  • After Large Imports
    Just brought in contacts from another system or marketing list? Validate before you use them.

  • On a Recurring Schedule
    Set a monthly or quarterly cadence to check for outdated or Invalid addresses—especially if your contact data is constantly growing or changing.


🔍 How to Use Validation Scores

Each email will return a score of Valid, Catch-all, or Invalid:

  • Valid – Safe to send; recent engagement detected.

  • Catch-all – Might work, but be cautious; may not be regularly monitored.

  • Invalid – Don’t send; this address is undeliverable or inactive.

Use filters in SigParser to:

  • Exclude Invalid contacts from exports or campaigns

  • Review Catch-all addresses manually (especially if they belong to high-value contacts)

  • Prioritize Valid contacts when creating segmented lists


📤 Exporting Clean Lists

After filtering based on validation scores:

  1. Go to the Contacts page

  2. Apply filters to isolate Valid contacts

  3. Click Export > Export to CSV

  4. Use your cleaned list in tools like MailChimp, HubSpot, or Constant Contact

This ensures you only target the best, most reliable contacts.


🧠 Pro Tips

  • Combine with Engagement Data: Use SigParser’s interaction metrics (emails + meetings) alongside validation scores for a more strategic view of contact health.

  • Tag Problem Records: Create a Custom Field like “Needs Review” to track Invalid or Catch-all contacts across your team.

  • Stay Proactive: Don’t wait until you get flagged—keeping lists healthy is easier than fixing a damaged sender reputation.
