At Profesional Hosting, we know the importance of our clients' emails reaching their destination. That's why Profesional Hosting has the SMTP Relay service, which guarantees delivery to different email operators and services.
However, we will explain some simple steps with which we can maintain and clean up the popularity of your IP to avoid your emails from being blacklisted.
We will leave you with our recommendations to avoid blacklists!
First, we will talk about the 3 main factors that condition the delivery of our email shipments:
The reputation of the sending IP
The reputation of the sender's domain and/or account
The content of the email itself
Our SMTP Relay service
This service guarantees the reputation of the sending IPs, which in turn guarantees delivery to the recipient's mailbox as much as possible. It also blocks, if necessary, dangerous shipments such as:
Shipments with suspicious virus, malware, and spam content.
Shipments from nonexistent accounts.
In many cases, it is even capable of blocking an infected website or mailbox without affecting the connectivity of the rest of the domain and/or server.
The reputation of the domain/account
It will depend on whether your shipments are accepted, responded to, or bounced from nonexistent accounts or marked as spam by recipients, among others.
The content
If it is a commercial email, it should include a list-unsubscribe header with an email address where the recipient can request to unsubscribe from the list.
Avoid repeating punctuation marks
Avoid writing in all caps (it is considered shouting)
Personalize the email as much as possible.
Never attach executable files.
Always include an explanatory text for attached files (do not send empty emails with attached files)
As your reputation increases, your emails will be delivered better to their destination, and you will not be punished as severely for not complying with a rule punctually.
This is not a complete list by any means, but a guide to some of the steps you can take to help you in your efforts to get your emails to their destination. You will find complete articles with more suggestions that may be helpful on Google.
The advantages of using multiple email domains for the store, automatic communications, and personalized company communications are also worth mentioning.
