The inbox placement of your newsletter largely depends on the recipient email clients' spam filters.

Email providers like Gmail and Microsoft apply sophisticated filters that evaluate email content, sender reputation, and recipient engagement to determine placement.

For example, Gmail spam filters scan your newsletters' content, and if it looks like a Promotional email - it is directed to the "Promotions" tab.

The above also applies to Spam. If a newsletter looks like spam - it goes to spam.
​
On top of the above, other factors like your sender domain reputation and email subscribers' engagement are considered by email clients.

Maintaining email list hygiene, ensuring a balanced content structure, and actively encouraging higher subscriber engagement can further enhance deliverability.

To maximize your deliverability and ensure your emails land where they should, consider these comprehensive strategies.

  • The most important step is authenticating your domain; if you haven't done that yet, here's a quick guide:

Details like setting up SPF, DKIM, and DMARC protocols are essential for protecting your domain and improving trust with email providers.

  • By authenticating your domain, you'll notice a considerable improvement in your campaign's deliverability. Over time (and following general best practices) your newsletters will start reaching the main inbox with ease.

Regular monitoring of delivery reports and optimizing campaigns based on data are also key to maintaining and improving engagement.
