Cold Email & Sequencing

Cold email software sends outbound sequences from mailboxes you control, handles follow-up logic, and stops a thread the moment someone replies. It is bought by outbound teams and lead generation agencies sending at volumes that break a normal inbox, and by founders who want reply tracking without a full sales suite. Three shapes exist inside the category: lightweight senders that connect a handful of mailboxes and run linear steps, high volume platforms built around mailbox and inbox rotation across hundreds of accounts, and sequencers bundled into a wider engagement or CRM product. Deliverability features sit right next to sending here: warmup, spintax, custom tracking domains, and per mailbox daily caps. Compare the pricing model first, since some vendors charge per mailbox or per contact uploaded while others price per user with sending uncapped, then check how much of the sending infrastructure you still have to buy separately.
