Pick the trigger before you pick the template

The weakest sequences start with "what shall we say?" The strong ones start with "why are we reaching out to this person right now?" That reason is the trigger, and it is the single biggest lever on reply rate. No template rescues a message that has no reason to exist.

Triggers come in tiers, and the data on the gap between them is stark. The strongest are behavioural and recent: they hired a head of revenue last week, opened a second office, pushed a pricing page live, downloaded your guide yesterday. Emails that reference a specific buying signal, a funding round, a leadership change, a hiring surge, achieve response rates of 15 to 25%, roughly a fivefold lift over the 3 to 5% you get from a generic ICP send (Prospeo, The Digital Bloom). The next tier is firmographic and stable: they match your best customer on size, model and stack, so the relevance is structural even without an event. The weakest tier, the one most teams default to, is "they exist and they are in our ICP", which is no trigger at all.

Build your sequences around the tier you can actually detect at scale. If you can reliably spot a hiring signal or a funding event, that is your entry condition and the first line writes itself. If all you have is firmographic fit, accept it and lean hard on a sharp point of view rather than pretending you saw an event you did not.

The discipline is to let the trigger gate the list. A contact who does not match a real trigger does not enter the sequence. This feels restrictive and it is supposed to: you are trading volume for the right to be relevant, which is the only trade that moves reply rate. Decide which accounts even qualify upstream with a lead scoring model that earns its keep, and source those signals deliberately rather than scraping a list and hoping.
