used to use https://meetalfred.com/ for linkedin automation (back then it was called askleonard). The messaging is based on filters so you might message a few folks that isn’t in your niche.

I use Hubspot (CRM) , Alfred for LI outreach. Lemwarm for warmup tool. Apollo for DB and email validation I also use phantombuster via API to enrich HubSpot. I hook all of these together with our platform Pandaflow.io

May be a bit biased but Woodpecker works great for outreach, warm up and verification For database I really like Apollo and GetProspect

I've been using: MeetAlfred - LI outreach Gmass - Cold Email Seamless.ai - Leads NeverBounce - clean emails NuReply - automated first lines from AI Zoho CRM to tie it together
