[About clustering feature] "I feel so much more organized and in control of my mail again. There is much less clutter in my inbox and it takes me seconds to delete unwanted emails rather than endless minutes trying to organize it..."

In addition to conversation grouping, Eπvelope uses fuzzy logic techniques to find and group 'similar' emails letting you easily consume related emails or delete entire clusters.

MONEY INSIGHTS (Optimized for US users) Key money information from Receipts, Bills, Statements, Alerts is extracted and displayed within the mail timeline. HANDWRITTEN & PICTURE SIGNATURES Create handwritten signatures or insert your own logo / image in the signature REMINDERS Add a reminder to follow up on emails with convenient options or a specific date & time. SNIPPETS Create reusable pieces of text & images that you can insert into your mail responses or compositions. 1-TAP With just 1-Tap, Delete, Add a Reminder to Follow up, Flag / Unflag or Mark as Unread.

Crashes too often. Makes it unusable. Attached files are unseen until viewing the sent email. Disappointing. It has great potential. ### 1/5 — Defunct? *2018-08-23, version 1.7.6* Developer's website and support email address appear to be no longer active. ### 5/5 — Stellar! No issues, long time user *2018-08-09, version 1.7.6* I don't know why others are having issues. I have none, zero. Connecting Gmail is odd to add - you don't fill in login in the app. You hit the add button and it takes you to Gmail login interface. I use it on an iPhone 8 Plus, iPad Mini 3, and iPad Pros. No issues with crashing, connecting accounts, dealing with massive amounts of e-mails - I have 6 or more e-mail accounts including Gmail, Microsoft, Apple, and my own sever/websites e-mail accounts. For years. As I said, I've been using this app for many years. It went to and stays at GREAT, UNIQUE, and POWERFUL. The developer maintains it regularly, it's one of the only couple of iOS apps that I've been able to count on using long term and is still worth using over newer apps. ### 1/5 — Won’t load account *2017-10-04, version 1.7.4* Office365 won’t work. Tried 6 different accounts. Not ready for prime time. ### 4/5 — Love this app but... *2017-09-06, version 1.7.4* I love this app but it keeps crashing. I want to to work so please fix this issue. Not using gmail. ### 1/5 — Limited Options *2017-09-03, version 1.7.4* - Cannot attach files other than from Dropbox. No access to Google Drive or OneDrive files. - Doubles spaces everything including signature. Cannot correct this error. - No option for Auto BCC: ### 1/5 — Does not work with Gmail *2017-08-26, version 1.7.4* This does not work with GMail. Folders are not correct and can't delete emails properly. ### 1/5 — Just A bad app *2017-04-30, version 1.7.2* This app locked up on the setup. I tried 5 times to set up this app and every time it just locked up on the screen. How does this get past apple QC? Good thing it was free to try! ### 2/5 — Great concept BUT too many bugs 🐜 Needs a lot of work *2017-04-30, version 1.7.2* Sent them an email with the following questions and have yet to hear from them: Hi. I just downloaded your app and have a few questions. How do I delete old contacts with whom I no longer keep in contact? How do I change time zone? Mine is correct but incoming email is wrong unless it's the sender's time maybe ?? Can I get Envelope to integrate with my reminder app that is not default on iPad? Also, reminders not showing up on calendar (iPad default calendar) Can I change fonts? It also doesn't show my sent emails sometimes in the bubble window but when it does, there is no format to them, all words jumbled together with no paragraphs or they just disappear altogether. Also, no red notification number showing emails that have come in unless the default one has to be turned off first so not sure about that...and picture added t signature not showing up - just a little box where the picture should be. Emails also showing in the wrong order somehow. Lots of features though so if they work on it more then it may be useful. Really wanted to like this app but deleted it and went back to using default app in iPad. ### 2/5 — I like it!! But... *2017-04-30, version 1.7.2* I've been using gmail's In Box. I don't like the bright white look of that app, especially first thing in the morning, so this rich colorful app with a dark background suits me just fine. First off, they need to do some work on email threads. I have one thread with 8 conversations, but only 5 show up in Envelope. That is unacceptable in an email app, imho. So until they get that squared away, I will have to continue to use another app The text bubble quick response was cool, but I have a hard time reviewing my content for errors because the input/editing area is black font on dark gray background. I looked for color options in the settings, but if they're there, I couldn't find them. Why the dev team would settle on black over dark gray is beyond me. I'm still getting the hang of it. Didn't quite get how to leverage all the cool text formatting features (so simple to add bold or italics in a new draft) until I realized that in addition to the text bubble sort of quick response, I can also tap the "plus sign" and the compose icon to construct my reply in a full window. I can also add a brief sound clip, image, take a photo, or send a scribble. Love the versatile signature feature except that I'd like to have more than one signature, and I don't see how to do that, either. Still learning! I wanted to give this more stars but because of the black/gray I mentioned and the fact that some elements of email threads don't actually render I have to knock it down. I remain hopeful... ## Frequently asked questions about Envelope ### What does Envelope do? Envelope is an email client designed to help users manage their inboxes more effectively.
