How to Reduce Your Mailchimp Bill by Cleaning Your Mailing List
·2 min read
Most email marketing tools, Mailchimp included, price their plans by how many contacts you have. As your mailing list grows, so does the bill. But how many of those contacts can actually receive your email?
If a chunk of your list is dead addresses, you could be paying to store people who will never read a word. Here's how to find them and cut your costs.
Step 1: Check how your plan is billed
Look at your account and see how contacts are counted. Pricing rules change, so check Mailchimp's current policy rather than relying on old advice. In particular, find out whether archived or removed contacts still count toward your total.
Step 2: Export your audience
Download your contacts as a CSV file. Keep this as your backup.
Step 3: Verify the list with VerifyFlow
Pay for VerifyFlow to get your access code, then upload the file. It's a flat £20 per list, up to 1,000,000 rows, so you know the cost upfront. You'll get your addresses sorted into valid, invalid and catch-all.
Step 4: Remove the dead ends
Archive or delete the invalid addresses in your email tool. These are dead ends: they can't read your campaigns, so there's no marketing value in keeping them.
Step 5: Look at catch-all addresses separately
Catch-all addresses can't be confirmed either way. Don't remove them blindly. Send a small test first and keep the ones that engage.
Step 6: Retire the silent contacts
Beyond dead addresses, look at people who haven't opened anything for a long time. Send one friendly "still want to hear from us?" email, then let go of anyone who doesn't reply. A smaller list that engages is worth more than a big one that doesn't.
How much could you save?
It depends on your list and your plan. As a rough check, add up how many contacts you'd remove, then compare the monthly cost of that tier to your current one. If cleaning takes you down a pricing band, the £20 will usually pay for itself quickly.
Who benefits most
- Agencies and freelancers running lists for several clients.
- Online shops with years of old customer sign-ups.
- Charities and newsletters with long-standing supporter lists.
Final thoughts
A bigger mailing list isn't always a better one. Verify it with VerifyFlow, remove the dead ends, and make sure your email marketing budget is spent on people who can actually receive it.
