E-mail marketing is an effective way to keep in touch with your customers and generate new business leads. There are dozens of choices in email promoting that it’s overwhelming for some.
Only send messages to those you know. Mailing people who are not familiar with you or your product may come across as spam. This most likely will lead them to throw your email in the trash, which would mean your time was wasted.
Test out different subject lines with the same email. This gives you the information you need to figure out which subject lines garner higher open rates and which ones were simply ignored in subscribers’ inboxes.
