How to prevent quote emails from landing in Gmail's promotions tab?

Hey everyone! I’m working on a custom API for our CRM using FastAPI. We’re moving away from our old SMTP setup and now using Mailgun to send emails. The problem is all our test emails are ending up in the promotions tab in Gmail.

These aren’t spam or marketing emails. They’re quote emails that customers actually ask for. With our old SMTP system they went straight to the inbox. No problem there.

I’m on Mailgun’s free plan right now. Will paying for a better plan fix this? Or does Gmail just automatically put all Mailgun emails in promotions no matter what?

I’ve already set up the sending domain as mg.ourcompany.com like Mailgun suggests. But it’s not helping.

Has anyone else run into this? Any tips to get these important emails where they belong - in the main inbox? Thanks for any help!

I’ve dealt with this issue extensively in my work. One key factor often overlooked is the email’s content structure. Gmail analyzes the text-to-link ratio and the presence of certain keywords. Try reducing links and avoiding marketing-like phrases. Also, encourage recipients to move your emails to their primary inbox and engage with them. This trains Gmail’s algorithm over time. Consistency in sending patterns and gradually increasing volume can help too. Remember, it’s an ongoing process, not a one-time fix. Keep refining your approach based on delivery reports and user feedback.

hey, i’ve been through this too. try sending plain text emails, using a matching from address, and tweaking your content to seem more personal. this might help get your emails out of promotions and into the primary inbox.

I’ve encountered a similar issue before and learned that the problem is often not with Mailgun itself but with how Gmail sorts incoming messages. In my case, ensuring the ‘From’ address matches the domain and avoiding overly complex HTML helped a lot. I also made sure to implement proper authentication methods like SPF, DKIM, and DMARC. Personalizing the content so that emails appear more individual rather than bulk sends a positive signal to Gmail. It took some trial and error, but gradual adjustments brought noticeable improvement.
