Delete emails within a thread
Outlooks allows you to delete emails within a thread. This is helpful when there's some chat back and forth that isn't necessary to keep though the other emails in the chain need to stay
Automatic follow up if no reply
This could be a killer feature for Missive: https://www.ifnoreply.com/ :)
Option to not load remote images for untrusted senders
When clicking emails, avoid loading remote images by default unless the sender has been marked trusted (which can be done automatically if you reply or send any email to that address). Currently, all email loads remote images and this is a sure-fire way to send read receipts to spammers, flagging yourself as a real account > leading to even more spam.
Highlight terms in search results
The search function returns a list of conversations and emails containing the query but it doesn't highlight them inside the conversation. Conversations can be very long may not even load the portion containing the search terms.
Chat read receipts
As a team communication tool, it'd be helpful to see when my teammate has read my chat message. Not sure how this scales to many teammates, maybe similar to a group Messenger conversation? (showing people's faces at the last message they've read)
One click unsubscribe
Would love to see a one click unsubscribe feature that can be seen in polymail, etc.
Drop-down menu for Response variables
It'd be great to have an option for response variables in a drop-down style that users can add pre-defined options.
Custom highlight colors (or more, or remember last)
The "highlight text" background colors are all rather bright and call too much attention to the text. I usually want something more subtle. You allow custom colors, which is great, but sadly it's not remembered so I have to re-choose my preferred color every time. Any of these options would be great: Have Missive remember the last chosen custom color (maybe even the last X number of them) Add a row of lighter tinted colors Within settings, allow us to choose a custom palette (so I could have my muted yellow, baby blue, etc.) Thanks!
Mark as Spam
Need to be able to mark specific emails as spam, even if there is an existing reply taking place. Right now, if someone forwards me an email to verify if it's spam or not, I can't mark the email as spam. It gives me a warning and says that I would be marking my company as spam. In other words, if there is an ongoing email thread taking place (sometimes people reply to an email, then realize it's bad), I'd like to be able to choose the email that is spam and mark it specifically so we don't keep getting their emails. Otherwise I have to find a workaround to block them.
