To make sure you're only sending emails to the people who want to read them, clean up your email list so that it excludes recipients who haven't opened a certain amount of emails in the campaign's recent history. This makes sure your emails' open and clickthrough rates reflect only your most interested readers, allowing you to collect more effective data on what is and isn't working in each email you send.
The most advanced email marketing services offer custom workflows where you can specify triggers based on actions (such as opening an email or making a purchase) or on inaction (such as ignoring emails). With these services, you can also set up a series of emails (such as tutorials) to be sent to segments of users, and you can pause or stop a campaign at any time. You can also move contacts into new segments once they have completed tutorials.
Beyond that, avoid using all caps, too many exclamation marks, and hyperbolic phrases ("ACT NOW BEFORE TIME RUNS OUT!!!!"). Poorly formatted HTML in your emails can also hurt how they’re handled. Every spam filter is different, so an email might pass through one filter but get flagged by another. For more comprehensive info on how spam filters work and how to avoid them, check out this guide by MailChimp.
Getting started shouldn't be daunting. Generally, you'll know right away whether you like a user interface (UI) or not, and most of the contenders we reviewed offer free trials so you can poke around before dropping any cash. Luckily, most of these services have modern-looking graphics and uncluttered layouts. These are not the complex business software UIs of yesterday. Be careful, though, as some free trials require a credit card. This means you need to be sure to cancel your trial before you're billed if you're not happy with the service.

And that leads us right into understanding service pricing and packaging. The email marketing services we reviewed range from about $5 per month to as much as $20 per month for a range of features. Many email marketing plans include unlimited email sends each month and bill you based on the number of subscribers. If you have a small list, then look for a company that offers a free plan, a low-cost plan for several hundred subscribers, or even a pay-as-you-go plan. On the flip side, many of these services also offer high-volume plans with up to 100,000 or more contacts. Sometimes this requires a custom plan that has to be arranged directly with a sales rep. If you're willing to commit, then look for the companies that offer discounts if you pay yearly rather than monthly. A few offer also money-back guarantees.
