If you're inviting readers to download an ebook, for example, and you have a picture of the ebook included in the email, don't just hyperlink the text next to the image telling people to "download it here." Hyperlink the ebook's picture, too. People are drawn to images much more commonly than text, and you want to give your email subscribers as many options to get your ebook as you can.
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.
Last but not least, we believe helpful support is extremely important specially when it comes to email marketing software. As we mentioned earlier, MailChimp support is not very helpful. You don’t even get phone support unless you’re paying them minimum of $299 per month whereas our #1 pick, Constant Contact offers helpful live chat, email, and phone support to all customers.
