Mails Sent By Gmailapp Are Getting Into Spam Folder

I've been struggling this for a week but still don't see any light. My company is using a google form to collect users' orders, and then send them emails regarding their order usi

Solution 1:

There are a great many indicators that email providers use. A PayPal link can be suspicious because, well, it's asking for money!

The majority of spammers are lazy and have simple emails. I suggest padding out your email with a large footer, unsubscribe details (even if it's transactional) including the word 'unsubscribe', an address, a logo, and other verifying details such as business number.

There is no golden ticket that will get you through, unfortunately!

That's content.

Regarding the mail server:

If you've configured your server with SPF, DKIM, DMARC - and are enforcing DMARC compliance - then that is a very good start, but still doesn't ensure it will get through 100%. The server may need a warming up phase, and also the email provider will look at what rate your customers are opening and interacting with your email. You can try services like Postmark to ascertain whether it is a server issue instead of content.
