With the constant increase in the volume of emails exchanged each day, email service providers have developed increasingly sophisticated filters to distinguish legitimate emails from spam. For businesses and marketers, ensuring that email communications actually reach their target’s inbox has become a major challenge.

Structuring an effective communication strategy requires a thorough understanding of the mechanisms that govern anti-spam filters and rigorous application of good email sending practices. Let’s explore these tools and methods together to optimize the visibility of email communications.

Take care of the quality of the recipient list

Select carefully

The integrity of your contact list plays a crucial role in sender reputation. A list with inactive or incorrect addresses can significantly harm your performance. It is therefore essential to ensure that you obtain the consent of recipients and keep the list up to date, by removing unsubscribes and bounces.

Clean regularly

A good practice is to clean the list by eliminating addresses that have not interacted with your mailings over a significant period of time. This reduces the risk of being flagged as spam and preserves your engagement rate.

Write professional emails

Opt for clear and professional language

Using clear and unambiguous language is important. Spam filters can be triggered by excessive use of punctuation, capitalization or terms often associated with spam. Neat, polished writing is more likely to pass the filters.

Maintain a text/image balance

An email composed exclusively of images can arouse the suspicion of filters. Make sure to include enough text to accompany the visuals and use optimized quality images so as not to unnecessarily weigh down the email.

Don’t forget the technical aspects

Validate your domain

DKIM, SPF, and DMARC are security protocols that your business should have in place to validate the authenticity of its mailings and build a positive reputation with email providers. These technical configurations are key to ensuring that your emails are not perceived as fraudulent.

Use a clean domain name

Sending emails from an address associated with a professional domain name demonstrates your seriousness and contributes positively to your sending reputation.

Pay attention to the content of messages

Avoid content pitfalls

Certain words or phrases may trigger spam alerts. It is a good idea to analyze content before sending to ensure that it does not contain potentially problematic terms.
