What is email warming-up?

Email warm-up is a process that helps you build a good reputation for your business and website and allows you to have a higher deliverability rate which translates to lower spam rate, higher open rate, and more sales.

This consists of starting to send a small number of emails and then gradually increasing this number each day. This process is very important to establish a good reputation for your email in the sense that if you start sending a lot of emails on the first day, there is a high chance that you get labeled as spam.

When you begin using Foxx, you are automatically enrolled in a warming-up process.

How does this warming-up process work?
When you start using Foxx, you have a daily limit of 200 emails. As you send emails with Foxx, your activity is checked on a daily basis. During this check, if the number of emails you have sent in a day is close to your daily limit, we increase your limit so that you can send more emails the next day.

Here is an overview of how the limit can increase if you are actively using Foxx to send emails:

Day 1: 200

Day 2: 300

Day 5: 800

Day 10: 4.000

Day 15: 20.000

Day 20: 100.000

Day 24: 400.000

Depending on the number of emails you send daily, your warming-up period can then take 24 days or more. After this period, the number of emails you can send per day is only limited by your pricing plan.

The email limit is daily, but for more efficient warming up, the number of emails you can send is actually throttled per hour. Considering the previous example, on the first day, you can send up to 10 emails per hour. On day 15, you can send up to about 1.000 emails per hour and so on.

As your campaign is ongoing, your spam rate is checked, and the campaign is paused if its spam rate is high.

If you don't send emails for a certain period of time, we also reduce your email limit so that when you start sending emails again, they won't be considered spam.
