Should I exclude my existing subscribers from my Meta ads?
Short answer
Yes, once your list is big enough to matter. Export your subscriber emails, upload them to Meta as an audience, and exclude that audience from your newsletter campaigns so you stop paying to reach people who already signed up. Refresh the upload about every two weeks. It's a five to ten minute job.
Meta is very good at finding the kind of person who loves your newsletter. The catch is that it doesn't know who already subscribed. Left alone, it will keep spending your money on people who are already on the list.
"Otherwise Meta is going to be like, these 45 year old moms love the brand, and they're going to keep showing the ad to that same mom over and over, even though she already subscribed."
Why does it matter?
Your current subscribers are the people most likely to stop and click a newsletter ad. They already like you. Every one of those clicks is money spent on someone you already have.
The bigger your list, the bigger the waste. When a publication comes to me with a large organic list and wants to start Meta ads, uploading that list as an exclusion is the first thing I do, before the campaign goes live. For clients with a lot of subscribers I expect it to have a big impact.
When should I start excluding?
My advice:
- Under about 1,000 subscribers: don't stress about it.
- Around 2,000 to 3,000: start doing it and make it a habit.
- A big existing list: do it before you spend your first dollar.
The job takes ten minutes, so starting a little early costs you almost nothing.
How do you set it up?
- Export your subscriber list from your email platform. A basic export with the emails is enough.
- Upload it to Meta as an audience. Name it something obvious, like a do-not-advertise list.
- Exclude that audience in your newsletter campaigns.
- Set a reminder every two weeks for someone to spend five or ten minutes uploading a fresh export.
It's relatively straightforward. Like everything on the Meta platform, it's fiddlier than it should be. No single step is hard; there are just a lot of them. With clients I usually walk them through it live on a call rather than having them send me their list.
