Sometimes a candidate accidentally opt-outs, or changes their mind about opting out from receiving text messages from you. If the candidate wishes to opt back in then all they need to do is send 'START' OR 'YES' OR 'UNSTOP' to your Rectxt number and they'll automatically be eligible to receive text messages again from you :)
As part of TCPA compliance candidates should be given the option to opt-out of any text messages from recruiters. Rectxt natively offers this functionality so that you can remain compliant with best-practices. Learn more here.
