We include a signature ad in the free version of Mailtrack quite simply so that our business remains viable (no ads+no payment for our service=0 viability).
You can still remove the signature ad with Mailtrack Free and our tracking will still work, but if you do so you will receive a pop-up encouraging you to sign up to one of our paid plans.
