Have same airmail app for android devices as iPhone. Several have both OS and some use simultaneously like myself.

Title says it all, some other email clients have this feature and I use airmail on my Mac as well as my iPhone and would love to see this implemented into both clients. On the Mac client you are able to ctrl-a all of your emails (and then ctrl-click to deselect any you want to keep but I would love to see a button on the Mac as well as iPhone client. Doing well developers!

When discuss become too long, find new attachments very hard or impossible

I just want to have the ability to add html content to my signatures

option to encrypt like pgp

I believe, the IOS app should have a "no message preview" option on a lock screen, just like a default Apple Mail app. You see a notification on a lock screen, but you do not see a message preview.

Separate mail using gmail's tabs. Rather than only having inbox for a gmail account, use updates, promotions, etc., if they are used in my gmail account

I currently have to swipe twice for emails that I don't need to open and want to archive directly. Would be useful to either automatically mark as read all messages sent to archive or else have an action that does both that I can assign to a swipe.

When someone sends an image in the body of an email, I would really like to be able to save it to my device.

More modern notification sounds.
Better email signature options.
Better spellcheck system/option.

once you click on a mail in a conversation to open it up, you can't close it down again. This makes navigating long threads frustrating

When an email is sent to calendar, viewing it in Apple Calendar there is a URL link to open the email in AirMail. But opening it in Google Calendar, this link doesn't exist.

I send out the same email to several clients and new clients. It would be nice to have a template to send them. Thank you.

Would be great to have a today widget showing the subjects in the "Todo" folder

Marking all emails as read in Airmail in OS X does not remove the badge or notifications from the iOS app. Sync should be near instant.

I generally do not want all of my email stored locally. Perhaps Inbox and Starred folders (or selectable) could always be kept regardless of age. Otherwise, all emails older than an account specified range would be removed from local storage.

thought this will be available from day 1!

I get emails in multiple languages, it'd be really nice to have a 'send to Google translate' type of action.
