How many text until the lead is dead ??

I have about 70 numbers after the Halloween weekend a lot of them are cold but some do reply and I have about 3 forsure down to meet up this week and next week

How can I squeeze out more dates to get they're attention after I asked to meet up but some ignore me and I've down about 3-4 follow up texts

When should I stop cold turkey on these leads and just archive there number and focus on new leads or leads that actually reply and also what are some call outs I can do I'm trying the "why are you ignoring my

texts after the 3rd no response and after the no response the 4th time I say I think I saw you yesterday haha and I do get some responses back but I want to get as many dates as possible with all these leads
