How to fix the problem of emails going to customer spam boxes

Have you ever had this problem with your emails going to your customers’ spam boxes? If so, then this article should be of interest to you. We offer you three practical solutions to this problem, making you an essential customer.

In the daily life of businesses, it is common to send emails by email to customers or prospects. They are sometimes surprised at the lack of reaction from customers. However, the emails are likely directly redirected to the spam box of said customers. Several reasons can justify this impact which can have significant consequences on your business.

The reasons for redirecting emails to the spam box

Reason # 1  : Bad reputation of your mail server

Are you surprised by this reason? Above all, do not be, because it is one of the leading causes. If the reputation of your server is considered insufficient by the recipient mail servers, your messages are likely blocked or placed in a secondary directory of the spam box.

Reason # 2  : Your address has been added to the blacklist

Even if you are not used to sending emails regularly, your emails might be redirected directly to spam if your IP address was used by someone else to compose an email.

For example, if you are using Mailchimp to run your campaigns, obviously your emails are sent from their servers. So if another person uses your IP address to send emails, it could affect your ability to deliver your emails. And your IP address can register in the client’s blacklist.

Reason # 3  : Bad audience / Bad targeting

It may happen that the recipients of your emails do not want to receive them. In fact, if one of your contacts/s/s reports your email as being spam, even if this is not the case, the access provider will record it as a complaint. If it is repeated over a certain period, your subsequent emailing campaigns will have a good chance of ending up directly in the spam box.

Solutions to remedy the situation

Here are the 3 solutions we offer to avoid Spam filters:

Solution # 1  : Filter the contact list

You can filter your contact/s/s list if you do not want essential emails to go to spam. Indeed, there are effective means to determine which of your contacts is valid for your emailing campaign. For example, you can use email verification servers. It is quite simply a tool that allows you to filter the emails you receive through your website. You can use find out which email is valid or not.

Solution # 2  : Perform a 2-level validation

Each time a person subscribes to your newsletter, it is possible to send them an automatic message directly to ask them to validate your request to be added to your list of contacts/s/s. This will prevent any third party from using any email to subscribe to your newsletter.

Solution # 3  : Use SMTP servers (SendGrid example)

 The SMTP server ( Simple Mail Transfer Protocol ) is a communication protocol used to transfer emails to email servers. It is pretty easy to use. It allows your emails to be allowlisted. If you opt for these services, you will have the advantage that the receiving mail servers will identify them rather than focusing on your mails. This will make it easier for your customers to receive your emails in their inbox.


If you believe that your emails are blocked by spam filters from your customers and therefore do not arrive in the inbox, be aware that one of the reasons mentioned above may justify this. Do not hesitate to use our three solutions proposed in this article.
