Gone are the days when sending bulk mail was considered a great marketing solution. If you are still sending bulk mails, you are, in fact, putting your product and reputation at stake.
Why? Email Service Providers (ESPs) frown on sending unsolicited messages to the readers.
They want to ensure that their clients,i.e email readers, receive only the mails they actually “want”. ESPs make sure of this and have built systems to make sure unwanted emails are not sent to inbox but to the Spam folder.
Whats more, every time somebody reports your mail as spam, your credibility goes down bit by bit. Suppose, 1% of your subscribers report your mails as spam, then your emails may probably not reach other 99% too.
Understanding how the email ESPs work is very important if you want to ensure that your mails land in the inbox and generate response, in other words, keeps your audience engaged.
