Just my personal opinion, get off Thumbtack, ASAP.
If it works for you, more power to you. Just my opinion.
I've been off it for over 5 years and they still flood my email with leads that I don't want, while keeping my profile buried.
>>> Read the ToS *thoroughly* for any lead service you decide to use and if anything strikes you as odd, bail, as fast as you can! <<<
Thumbtack asked me to submit a copy of my electrical license, which I refused to do because it would have violated the municipality's terms against transference and I found a little phrase in their ToS that says anything I submit, they own, which means my license, any pictures I submit, everything.
Coincidentally, pages started popping up in my name on Pinterest and other sites that I DID NOT manage saying I offered services that I did not offer.
You put those pieces together yourself, lol.
