spam email
To summarize this article for me:

Emails are an essential marketing tool. But it can be frustrating to find that your messages end up in the spam folder, despite all your efforts to comply with regulations. 

By mastering the following strategies, you can increase your chances of staying in the inbox rather than slipping unnoticed into the spam folder. 

Stay proactive, adapt to your audience's needs, and maintain an impeccable sender reputation to ensure the continued success of your email marketing campaigns.

What is the “Spam” ?

The “Spam” folder (also known as “Junk” or “Unsolicited Email”) is a folder in your email inbox specifically designed to store unwanted or unsolicited messages. Email service providers' spam filters emails and attempt to identify those that appear to be spam.

Emails considered spam can include unsolicited advertising messages, scams, emails , or messages containing unwanted content . Spam filters use various techniques to detect these messages, including keyword analysis, verification of the sender's IP address, inspection of links and attachments, and more.

It is recommended to regularly check your “Spam” folder to ensure that legitimate emails have not been accidentally classified as spam. You can also configure your spam filters to improve their accuracy by flagging false positives (legitimate emails incorrectly classified as spam) or false negatives (unwanted emails that pass through the filter).

1 – Understanding the Graymail phenomenon

Graymail, that in-between space between legitimate and spam emails, can be a dangerous trap. Ensure your emails generate high engagement by monitoring signals such as opens, replies, and shares . Inbox providers evaluate the quality of your content based on these interactions.

2 – Respect the engagement signals 

Email providers like Gmail and Yahoo rely on engagement signals to determine email legitimacy. Maximize positive signals by creating engaging content . Avoid negative signals, such as spam complaints or low open rates , to maintain a good sender reputation.
