At Profesional Hosting, we know the importance of our clients' emails reaching their destination. That is why Profesional Hosting has a relay service with which we guarantee deliveries to different mail servers.
However, we will explain some simple steps with which we can maintain and clean up the popularity of your IP in order to prevent your emails from entering a blacklist.
We will leave you our recommendations to avoid blacklists!
First, we will talk about the 3 main factors that condition the sending of our emails:
The reputation of the sending IP
The reputation of the sender's domain/account
The content of the email itself
**Our relay service** guarantees the reputation of the sending IP, which ensures delivery to the final recipient's mailbox as much as possible. It also blocks on our own servers, avoiding harming your domain, such as:
Sending suspicious content of viruses, malware, and spam.
Sending from non-existent accounts.
Additionally, it is capable, in a large number of cases, of blocking an infected page or mailbox without affecting the connectivity of the rest of the domain/server.
**The reputation of the domain/account** will depend on whether your emails are accepted, replied to, bounced from non-existent accounts, or marked as spam by recipients, among others.
Finally, **the content**:
If it is a commercial email, it must include an unsubscribe header with an email address where the recipient can request and have the recipient's removal carried out.
Avoid repeating punctuation marks.
Avoid writing texts 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 better delivered to their destination, and you will not be punished as harshly 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 also find complete articles with more suggestions that can be helpful on Google.
The advantages of using multiple email domains for the store, automatic communications, and personalized company communications are also worth mentioning.
I hope this helps you get your emails to their destination.
