How we picked
We compared 15 email apps and kept the 11 that fit this guide. We don't test apps ourselves: features and prices come from each app's own site, and the order follows what independent reviewers recommend. No app pays to be listed or placed higher, and whether an app pays us a commission never changes its place.
Questions
How are these apps ranked?
Apps that independent "best of" roundups recommend come first, the most often recommended at the top; the rest follow with the best-known first. Every app listed meets this guide's needs.
Are these links sponsored?
Links to apps whose affiliate programs have approved Build Your Toolkit are affiliate links, marked as such, so we may earn a commission if you sign up for a paid plan. It doesn't change what you pay, and no app pays to be listed or placed higher.
Where do the prices come from?
From each app's own pricing page, on the date shown next to the price. Prices for email apps change often, so check the vendor's page before you buy.
