When/how should I know when it's time to stop following up and trying to convert a lead and when to just move on to new leads?

Hey guys, if I have a client who doesn't have SMS consent, but wants to reach out to his past customers for Google reviews, is email still an effective way to do that?

Does anyone use Close.com for their CRM for power dialing, etc.

So I am trying to add my client's card on file to their subaccount wallet without having to reach back out to them via phone to get it. I want to send them the secure payment link. I've been told this can be done, however, when I go into their subaccount, then billing, I get this:

So I went ahead and set up refilling for my sub accounts, but it's weird because as soon as I linked one sub account to one of the client's stripe accounts, it then activated the other sub account to Stripe even though I hadn't connected their Stripe to their subaccount yet...if that makes sense? Is there not a way to set up a wallet for the sub accounts or is that only for agencies? So how does the refilling work? Does it come out of my agency wallet, and then charges the sends them a bill or automatic charge from my account? I'm just so confused on all this sub account rebilling/wallet stuff.
