I’m back.


Updating my previous review. No other app just works for me like Astro! I’ve literally tried them all, including Boomerang, Trove/Notion, Outlook, Spark and my needs have lead me BACK to Astro. There are still key features missing and that’s why there is four stars instead of five but the lack features don’t outweigh the need for me with an app like this!

Love love love Astro mail. Love the Astrobot AI that helps me get to inbox zero, helps me to answer important emails and lets me know when an email has been opened and much much more! Very easy and simple to work, yet powerful. However, as advanced and powerful as it is it lacks a significant feature that nearly every other email app has, the ability to add ANY email. It’s missing out. I will admit It was one of the reasons I switched my business email to google apps just to use this but it doesn’t work with my native work email and for a non profit I work for so i causes me to have two mail Apps which defeats the purpose! So I just use Outlook which is also amazing but lacks the state of the art features. Hopefully astro mail will step it up, otherwise it’s a good app but with the most important thing missing, it’s just another app that takes up space.

Developer Response

Thanks for this feedback. Our first priorities are the business email services, Gmail/GSuite and Office 365 and we do plan to support additional services such as iCloud,, Hotmail, Yahoo Mail and FastMail, although our timing is uncertain.

Light years ahead


I normally don’t write reviews. But I felt the need in this case. I’ve tried at least six premium email apps and Astro is in a league by itself. It does all the work. It is constantly in the background looking for patterns of opened and unopened emails. Asking me if I want to unsubscribe to unsolicited junk mails that are in my inbox. And all I have to do is select yes or no and it does the rest of the work. It asks if emails fromThe same sender can be collected and archived and all I have to do is press yes or no. As I said it does all the work. I don’t have to look for the unsubscribe button at the bottom of the email, Astro does it for me. And these are just some of the basic things that it does. As I said in my intro, Astro is the way that all email will be one day but it is the only one that is available in the market today. If your mailbox is bulging at the seams there is no cure but to try this out. I guarantee you’ll be pleasantly surprised.

I regrettably have to give it just two stars


I was SOO excited about this app and all of its promise. All of the fantastically thoughtful features. And I submit, this is a very thoughtfully designed email app. However, two things for me... (and I’m SURE there would be plenty more if I dove into it more): There seems to be NO icon. NONE! It doesn’t reside anywhere other than in the two finger swipe down IF (IF!) you have recently used it. There was no icon for it to be found anywhere on my phone. And I really looked. Why would this make any sense? Minimalistic design? I don’t know, but I’d sure need an explanation. And second and more problematic for me is that this app does not allow use of iCloud email addresses. And likewise, they only allow Office 365 and Gmail. THAT is limiting. I need iCloud email account access in order to make real use of this app. I have a Gmail account, and I use it a lot. But, that’s not all I use.

The things I’ve named I’m sure are easy fixes for Astro. And as soon as they remedy them I will be prompt in raising my review accordingly.
