Picking and assembling the outreach stack. Finders, senders, mailboxes and scrapers, what each one is worth, and where building beats buying.
Most SMTP provider comparisons rank relays on price per thousand and uptime. For cold outbound the first question is different: whether the provider's own terms permit the list you intend to send to, and most transactional relays do not.
B2B data providers sell contact, firmographic and intent data. There is a fourth kind — a dated event on one named store — that is almost never on the shelf, and the reason is structural.
Email infrastructure is the layer under the decision: domains, mailboxes, DNS and the sending server. It decides whether a message can arrive, and nothing about whether it was worth sending.
Cold email software is the sending layer of an outbound stack. It does not decide who enters the sequence, and buying more of it does not fix a list that had no reason to be written to.
Email deliverability tools measure the sending side: authentication, reputation, spam rate, blocklists. None of them can tell you whether the store you are about to email had any reason to hear from you.
Sales enablement assumes a bench of reps to enable. For a three-person agency, two jobs survive that constraint: choosing which stores to touch this week, and having the opening written from a real event.
