Improving Email Marketing results is a long process and requires a lot of consistency in terms of database maintenance.The main reason for the low open rate is the direct arrival in the SPAM folder, but why does this happen? Lets start by the beginning; anti spam filters.
What are spam filters?
The anti spam filters refer to the algorithms used by webmail servers to determine what is spam (SPAM) and avoid annoying users.
These filters work through a scoring system that determines the degree of spam that an email contains. They are based on criteria where every word and every detail counts.
Anti spam filter criteria
We have technical and content criteria, both are important and it helps to know how they affect delivery results.
Technical criteria gulf email list Black lists: It is where those emails with IP addresses that have been classified as spam due to unauthorized sending or because they contain viruses in their messages end.
Historical analysis: Filters analyze the sending history to make sure before marking an email as spam. In this way, those who always send massive shipments and with high spam or complaint rates are penalized.
Server reputation: The Email Marketing provider is important, as well as the delivery structure it has.Volume of submissions: Excessive size of the mailing list can negatively affect, that is, we could be considered spammers. In addition, if many emails are sent to the same domain it can be classified as a cyber attack. It is important to establish a shipping schedule so as not to exceed certain limits.Sending speed: If the shipment is made in the same round, in the same hour, we are more likely to be marked as spam. I recommend doing a very progressive delivery, it is something that hardly affects a campaign. Some providers, like Mailchimp, have the option to send in parts.HTML code: It is important that the HTML code is clean and clear, without errorsContent criteria
Bayesian filters: They use the history to detect words or paragraphs that are repeatedly repeated in several emails. We should not insist with the same message to the same users, since it can be considered spam.Number of images: Excessive images do not like filters, the lower the image / text ratio the better. The “white” images are the most penalized.

With these 4 basic tips you can greatly improve the opening rate of your campaigns:
We must try to get users receiving emails to add us to their contact list . This will add a lot of quality to our delivery and build a good reputation for the sending IP or with the webmail server. It is certainly not easy, but it can be tried.
Improve sender and subject
It is the first thing a user is going to fixate on, if this is not right they will not open the email.
A very good option for the sender is to use a verified own domain .
As for the subject, it should be short and include the name of a commercial and then the company name , for example: “Laura from Nike”. Forget overly commercial messages.
data base maintenanceThe quality of the list is essential to achieve good open rates . If we have many emails that are clearly disinterested in our communication, they will not only harm this campaign, but future ones …Buying BBDD is illegal and unethical, but it is also not going to bring us good long-term results.

Image / text ratio: There must be a balance between the amount of images and text. Also, the images should always be responsive.
Shipping time: Do it at normal hours, never at dawn. It is interesting to have the Email Marketing tool configured with the time of the main destination country.
Links: These should point to reputable and quality domains.
Light images: If we reduce the size of the images we are more likely to skip the anti spam filters.
Capital letters: Do not use them unless “brand” is mandatory. Above all we should not use them to highlight words like “SEX”, “FREE”, …
Remember that before making a shipment it is advisable to carry out an anti spam test . Sometimes it is offered by the Email Marketing platform itself and other times we will have to look for external tools. Some like Mailchimp and Send it Simple have it integrated.
