What is a good email deliverability rate?
100/100 is a good email deliverability rate although it’s sometimes challenging to get to 100 but it’s possible with Folderly. If you are within 80-100 then you are doing good. Make sure you don’t send your emails out if you are below 70.
What does 70/100 email deliverability rating mean?
It’s simple, out of 100 emails that you send to multiple email service providers only 70 are delivered to inboxes and the remaining 30 ended up in the spam folders. You should increase your email deliverability rating to maximize the inbox delivery rate to 100.
