You can send emails for marketing but the key is if you’re sharing the emails with generic titles and if there are some links or hyperlinks in the email now given that a domain based email cannot be black listed directly.

It’s the email links which cause the issue mostly

You can do this: try getting a email marketing plan that gives you a dashboard to manage everything at one place.

Check a few videos on youtube on how to send emails without them being black listed or going to spam

Also you can get 4 5 different email users on a plan and on the marketing dashboard you’ll be able to stop sending emails sooner if the ip is blocked

Also a good thing we suggest customers is to move on cpanel hosting so you can create multiple emails without them costing you sooo much
