Half Of The Invoices We Send Go To Gmail Spam Folder

We getting many phone calls, because around half of the order invoices we send going to gmail spam folder, and clients do not see them.
Anyone has any suggestion what to do? we getting tired to tell clients "check your spam folder"
Any suggestion would be appreciated.

Aer you using smtp?

Aside from SMTP, setting up DKIM, SPF, and DMARC in DNS manager will help.

Check if your IP for reverse DNS record is properly configured. And of course use recommendations from post#3.

and afterwords try again with spam testing tool to see if it helps.

Have the same issue. Using via sendmail program. Everything is setup properly. No blacklisted. Below a test email picture but issue still:

Have you considered registring for Google Postmark? In most cases verifying your domain there should do the trick. Also, do mind that domain-age and volume is a significant factor when it comes to this.

There are a few remarks that could be made though:

1. Make sure that your phrases actually make sense (no spelling mistakes and such);

2. Including personal info directly in the HTML can boost your score when used correctly;

3. Too much HTML will always make you end up in the spam box;

4. Make sure you are signing emails with DKIM (DomainKeys Identified Mail), simple DNS won't do anything;

5. Use dmarc (Domain-based Message Authentication);

6. Make sure you have setup spf correctly (include Google!): 'v=spf1 include:_spf.google.com ip4:[your mail IPv4] ~all' -> becomes 'v=spf1 include:_spf.google.com ip4:0.0.0.0 ~all';

7. If there are inconsistencies in the “from” address and “reply to” address and domains, emails will be filtered as spam;

8. If users dont interact with your e-mails the chance of your e-mails being marked as spam will become significantly higher (engagement metrics);

9. Use a dedicated IP, a shared host will definitely impact your chance of ending up in the spam folder in a negative fashion;

10. Implement a 'dont e-mail me' or 'unsubscribe' button in all your e-mails. Google also checks for this very thoroughly, if these are not present and someone ends up marking your e-mail as spam, it will also greatly increase your chance of ending up in the spam folder of others.

If you have any other questions, please let me know.
