FAQPage Schema
What is email list hygiene and why is it important for deliverability?

Email list hygiene is the practice of validating addresses, managing suppressions, and sunsetting inactive contacts to reduce bounces and spam complaints. Maintaining clean lists protects your sender reputation and ensures strong inbox placement for marketing and transactional emails.

How do I validate email addresses at signup to reduce hard bounces?

To validate email addresses at signup, enforce rigorous validation checks during the import workflow to catch hard bounces and trap addresses before they enter your database. This prevents deliverability risk by stopping invalid contacts from damaging your domain reputation.

How do I manage suppression lists and sunset inactive email contacts?

Manage suppression lists and sunset inactive contacts by maintaining a single source of truth for do-not-contact records with documented reasons. Apply sunset policies to inactive subscribers to enforce list hygiene and minimize deliverability risk across your marketing campaigns.

What is the best way to vet imported email lists before sending?

The best way to vet imported email lists is to run controlled tests and apply validation checks during the import workflow to monitor impact. Vetted imports prevent unverified addresses from causing bounces and harming your sender reputation before you launch full campaigns.

How do I run a starter audit on my current email lists?

Run a starter audit on your current email lists to identify hard bounces and existing suppressions. This audit provides clear risk-aware decision guidance by evaluating validation integrity and highlighting contacts that require sunsetting or removal from your marketing lists.
