Its a good question - Im not sure there is an exact answer as to what works best now. But a few things that Im experiencing:
With the new challenges, ensuring you have enough volume of outreach is essential. More = Similar results to previous times.
Personalized outreach is the only way to go.
Webinars are working well for us. Just a couple of follow up discussions are making the event worthwhile.
slowing the process down, email/linkedin connect etc, BUT offering the prospect something first. E.g we have a report / a case study from your industry etc. Def dont ask for time straight away now.
FYI im using Amplemarket now for my prospecting. Its getting me similar results but with a lot less time. Also takes care of fhe mailbox warm up and protection which is a b*ll ache otherwise.
BTW - Post Discovery call, im using Storylane for instant custom demo experiences. Saves me a lot of time as it shows the prospects activity and behaviour on the demo.
For additional or faster mailbox warmup, instantly still works very well in just two weeks.
Good luck!
