Spam filters sort every email into inbox, promotions, or spam based on signals your server sends before anyone actually reads the message. Send from a free Gmail address with no setup behind it, and you look like a stranger to that filter.
In plain English
A spam filter is a bouncer checking IDs at the door before anyone gets inside. Show up with no ID, which is what a bare free email address looks like, and you get turned away no matter how good your message is.
How to land in the inbox
Send from your own domain
A matching business domain reads as legitimate instead of anonymous.
Add SPF, DKIM, and DMARC
These are records that vouch for you and prove the email is really from you.
Keep your list clean
Emailing addresses that bounce or never open drags down your reputation.
Worth remembering
Validity tracked trillions of emails and found global inbox placement sits at 87%, meaning one in eight never arrives.
That is across trillions of real emails sent, not a small sample. And it does not matter how good the writing inside is: a message filed under spam is one nobody ever sees.
What to do about it
