A: We want you using Mailvio every day for as long as you want. To help you get the best results from Mailvio, we have set up a unique proprietary account warmup system that will help you inbox better for the long-term. You will get 250 credits on Day 1. Based on your mailing performance, we will double it up. We will keep doing this until you hit 10,000 credits (note that if you spam or mail scrubbed lists, your performance will be bad and your daily credit score will be lower). After 10,000 credits, your daily limits will continue to change based on your email performance.
Essentially from there on, you CAN send unlimited emails, but that number is still dictated by how warmed up your account is. The more you use, and the better emails you send, the more emails you can send :)
