Hello Nikola!

First I must say I LOVE your plugin easy-appointments, I have not yet tested it for my company but privately it works wonders! 

I do however have ONE problem :( and I was thinking maybe you know how to fix it :)

my custom made emails for <pending> <Reservation> etc etc sends to the customer just as they should BUT

I've entered DLVRY@taxijamtland.se as the sender, which it does show as

But not right away, first you got to click the email and THEN you see DLVRY@taxijamtland, as the sender in quite small text 
in the example Below I shall type how the message appears in the INBOX

WORDPRESS               Reservation #14 is now pending, we will get back to you etc...

it should say

DLVRY Taxi                   Reservation #14 blablablablabla

why does it send as WORDPRESS? :( how do I change that? as said above you have to first click the mail and THEN u see DLVRY taxi. but it should be DLVRY taxi from the start :(
