How to Clean Your Constant Contact Email List

Constant Contact works better when the list going into the campaign is worth trusting.

That means cleaning before the send, not after the bounce report.

A practical workflow

1. export the list or segment as CSV
2. upload it to Verify List
3. remove undeliverable
4. review risky
5. suppress or remove the weak addresses in Constant Contact

Why this matters

For many Constant Contact users, the audience includes:

• small business contacts
• nonprofit contacts
• older local mailing lists
• periodically imported CSVs

Those are exactly the environments where list drift builds up quietly.
