How often is the data updated?

Unfortunately, Substack changed their platform so that the subscriber count column can no longer be updated.

Can I get a refund?

Yes, of course. If you're not satisfied, you get your money back, no questions asked.

How accurate is the data?

All numbers come directly from Substack. This, however, does not necessarily mean that they're 100% accurate. There are occasional odd outliers which in most cases can be traced back to bugs on the Substack platform. But if you find anything in the database that looks off, please reach out and I'll try to fix the problem as soon as possible.

Are all Substack newsletters included in the database?

Probably. Since Substack does not publish official numbers on the total number of newsletters that are published on its platform, I can't be 100% sure that the database contains all of them. However, I tried my best to collect information on as many newsletters as possible and at the very least, all popular ones are included.

If I cancel my subscription, will I still have access to the data?

Yes, of course. You just won't receive any updates once the subscription period ends.

Do I need programming skills to use Newsletter Spy effectively?

No. All data is made available through Airtable and thus it's easy to create custom filters without coding skills.

Below is a short tutorial that explains the usage of the Newsletter Spy database.
