I research relevant companies & contacts using LinkedIn Sales navigator & old leads in Salesforce.
I use ZoomINFO to get email & mobile data in to Salesforce after finding the right contacts.
I use Salesloft to run my cadences.
I also track a lot of my activity & who I’ve pulled through in google docs. Eg if anyone is a “do not contact”, I can’t put them in a cadence so I have to do the steps manually, so need a way of tracking it.
