Maintaining a clean inbox free of spam and clutter is top of mind for many, so I looked for apps that included some degree of spam filters, cleanup suggestions, and security options. They also tend to charge a monthly fee, and while there are paid apps on this list, I generally avoided apps that required expensive subscriptions. While these are useful for organizations, they're needlessly complicated for day-to-day emailing. Since we're focusing on the iPhone, which you're likely using for personal use rather than intense work, I rejected any primarily team-focused or collaborative email apps, like Front. An Apple Watch companion app, however, was a bonus. I wanted to showcase email apps that could be the only way you accessed your email if you wanted. I also focused on standalone email apps for iPhone, rather than apps that are really just add-ons for a web or desktop app. For more details on our process, read the full rundown of how we select apps to feature on the Zapier blog.įor starters, with one or two exceptions, I only considered apps that supported all the major email providers, like Gmail, Yahoo Mail, iCloud Mail, and IMAP accounts. We're never paid for placement in our articles from any app or for links to any site-we value the trust readers put in us to offer authentic evaluations of the categories and apps we review.

We spend dozens of hours researching and testing apps, using each app as it's intended to be used and evaluating it against the criteria we set for the category.

All of our best apps roundups are written by humans who've spent much of their careers using, testing, and writing about software.
