Cold email agencies for manufacturers
3 agencies in the index offer cold email for manufacturers. Ranked by the evidence on record, the first three are Belkins (Dover, US, from $5,000 a month), SalesRoads (Fort Lauderdale, US, from $6,950 a month) and Callbox (Encino, US). Results depend as much on list quality and sending infrastructure as on copy, so ask who owns the domains, inboxes and data when the engagement ends. Buyers are engineers, plant managers and procurement teams, many of whom still answer the phone, which is why phone-led agencies do well here. 2 of the 3 publish a monthly minimum, from $5,000 to $6,950, with a median of $5,975. 1 offers pay-per-meeting pricing and 0 offer pay-per-lead; the rest work on a retainer or do not say. Besides cold email, the services most often offered here are appointment setting, cold calling and LinkedIn outreach. 0 build on Clay, 1 works inside HubSpot and 2 use their own or undisclosed tools. 3 have a Clutch or G2 rating on file with the date it was read. Before signing, ask for a sample sequence, the definition of a qualified meeting and who owns the domains and data afterward.
