I wrote about a Snippet that you can use in your welcome email to get people to white list you, so you don’t end up in the promotions tab, but there are other few things that you can do and most avoid to not end up there.
 
Snippet
 
If you don't want my emails to land on the promotion tab, do the following: ● Gmail Browser - Drag and drop this email into the "Primary" tab ● Gmail App - Hit the 3 dots at the top right corner > click "Move to" then "Primary" ● Apple Mail - Tap on my email address at the top (next to “From:”) > "Add to VIP"
 
 
Do
Add the snippet in your welcome email
As mentioned before, you can add a snippet that will lead people to white list you so you don’t end up in the promotionals tab.
Add the snippet in the footer of your email
You can also be a little bit more insistent, and encourage people to whitelist you every time you send them an email.
Here’s an example from Justin Scott’s email newsletter:

Encourage people to reply back
If you email like a human, you will get replies like a human would.
 
If you display normal activity like exchanging emails, there’s a better chance that you won’t be considered a spam sender in the future.
Use Google Workspace
If you've registered (or transferred) your email to Google Domains, you have the option to add Google Workspace (former G-suite) to your email for only $6/month.
 
That will increase Google's trust in your emails.
Avoid
Trigger words (Both in subject lines and in your email copy)
 
Some words will instantly tag your email as a spam email and will send you to the promotional tabs.
 
If you ever notice a sudden drop in your email open rates, there’s a good chance you’ve used one of these words in that given email.
 
Here's a list:
 
  • The word ‘Money’ or everything related (that’s why a lot of people use moolah or dough)
  • $$$ (dollar sign)
  • WORDS IN CAPS
  • Excessive punctuation like “!!!” or “???”
  • Use the “Fire” emoji (others aren’t as bad)
 
A single use of the word will not get you to the spam folder, but using multiple spam words will.
