Mark all mesages from one sender

[lexxm6]

I need mark and remoove msgs from one sender, how can I do this?

[StR]

Try searching for the string that is unique to that sender (e.g. username@domain).
Then with the list of the results, select one -> select all,  delete.

You can also do Menu -> Sort -> by sender so they're all together.

But no there is no "automatic" way to do this, sorry.

Re: I use swiping action "search by contact" limited to sender to retrieve all messages from one sender, then select all.

Good one!

You can assign this swipe action in app settings -> swiping.
