Email deliverability is essential for anybody and everybody who’s using email to send important messages — whether you’re sending cold emails to thousands of prospective clients or sending a birthday invitation to a dozen friends.
If your emails don’t wind up in your recipients’ inboxes — and instead go to the Gmail promotions tab or, worse, the spam folder — your chances of campaign success plummet.
