When you send out a lot of emails at once, you want your system to work effectively. SendMails.io has a feature called Server Rotation that helps with this. It uses a system called “Fitness” to decide which server to use when sending out emails.
What is Server Rotation? #
Server Rotation is a way to spread out the task of sending emails across different servers. This makes the process smoother and more efficient.
What does “Fitness” mean? #
Each server is given a “Fitness” score in SendMails.io. This score tells us how likely it is that a server will be used to send an email. A server with a high Fitness score is more likely to be chosen.
Let’s take a look at a couple of examples:
Example 1: #
Imagine we have two servers:
- SMTP Server 1: Fitness score = 100
- SMTP Server 2: Fitness score = 50
If SendMails.io has to send an email, it’s more likely to pick Server 1. This is because it has a higher Fitness score. But remember, it’s not guaranteed – it’s just more likely.
Example 2: #
Here’s a different example:
- SMTP Server 1: Fitness score = 90
- SMTP Server 2: Fitness score = 10
In this case, out of every 100 emails sent, about 90 would be sent from Server 1, and 10 would be sent from Server 2.
It’s important to remember that Fitness doesn’t tell us exactly how many emails each server will send. It just gives us an idea of which server is more likely to be chosen.
Why is Server Rotation useful? #
Server Rotation is really useful when you need to send a lot of emails. It spreads out the work across different servers, making everything run more smoothly and efficiently.
Plus, it can stop any one server from sending too many emails and being mistaken for spam. This helps to make sure your emails are more likely to get through to people.
We hope this guide has helped you understand Server Rotation and Fitness in SendMails.io. Give it a go next time you need to send a lot of emails!
