As a platform dedicated to helping writers build trusting relationships with their readers, we take the quality of imported email lists seriously.
Spam complaints can damage deliverability for our entire writer community and prevent publishers from reaching their audiences.
What our team will do
To help keep deliverability great for all publishers across Substack, we may require a brief manual verification for large imported email lists.
How long will this take?
We're dedicated to making this process quick and efficient, but please allow one business day for your list to be verified.
