Nothing's worse than getting an emailed coupon for something you bought last week, or an over-the-top sales pitch seconds after signing up on a site. Make sure that your triggers are all laid out (based on the list segments in step 1), and that each email in your campaign is directly related to a trigger. Users should always understand why they're getting an email.

Drip campaigns, as mentioned above, are automated sets of emails that go out based on specific timelines or user actions. They enable you to stay in touch with groups of people based on events like when a user signs up for an account or how often that user visits your site. Each time a drip email is sent out, it comes from a queue of already-written emails—there's no need to manually write and send each one. They can even be personalized with your contacts' name, company info, and more.
Whether you're onboarding a new customer or keeping a user engaged, the sequence of your sends plays a crucial role in the success of each campaign. Consider how much information your target user needs, when he or she might need it, and why. Over on his blog, Jason Delodovici wrote a great post about a drip campaign that he spearheaded, noting the order he chose for each email—from signup to sale—and why.
