Most popular email marketing services offer functionality that strikes a recipient from a list once a certain number of emails to a specific recipient ‘bounced’ back as undeliverable. Don’t be overeager to remove a subscriber, though; there are valid reasons why an email cannot be delivered. Consider only removing such a subscriber after four or five “bounces”.
Double-check your email blast. After you've written your email blast, you should go over it again for grammar and spelling errors. An excellent way to help you edit your email is to send it to colleagues to ensure that there aren't any factual or grammatical mistakes, and to make sure that the messaging stays on brand. Ask people on your team to look over your blast and provide you with feedback.
Using the word blast says a lot about how you view email marketing. And because so many of us are so very touchy about being characterized as spammers (or just feel bad about “bothering” our subscribers) even using a word that leans toward sounding like spam bothers us. Remember that there are always two definitions of spam. There’s the email marketers’ definition (the CAN-SPAM Act of 2013 definition), and then there’s the consumer definition. The consumer definition of spam is simple and complete: It’s email they don’t want.
Julie Ewald recommends moving away from sending generic content to your whole email list via e-blast entirely. With a little elbow grease, you can utilize segmentation and start sending off tailored messages to each of your lists with content that’s relevant, valuable, and designed to resonate with the kind of recipients that make up each segment.
