The follow-up sequence that decides the value
The giveaway determines who you met. The follow-up determines whether it was worth anything. The sequence below is the shape that works for a B2B event giveaway, and the timings matter more than the copy.
Day 0, within twenty-four hours of closing. One message per person, not a broadcast to the whole list. It acknowledges the conversation, references the specific thing discussed — the requirement they mentioned, the product they asked about, the session they attended — and states one specific next step with two options. The purpose is to reopen the conversation while it is still warm, not to qualify further. Contacts who asked for nothing beyond the item are put into a lower-intensity track and are not sent this message; sending it to them is what makes the first message a broadcast.
Days 2 to 4. The useful content, sent once. A case study, a technical reference, a pricing structure or a comparison relevant to what the person asked about. This message carries no ask. Its job is to be useful enough that it gets forwarded internally, which is where B2B buying processes actually move.
Day 7 to 9. The single qualification question, asked once, in the context of the content that was just sent. Not a meeting request and not a discovery call; a question that requires a person to answer rather than a person to forward. The contacts who answer here are the ones with a live interest, and the ones who do not are usually a timing problem rather than a quality problem.
Day 21. A closing note with a concrete offer: a call at a stated time, a sample, a specification review, a visit. Followed by an explicit statement that the file will be closed unless they respond, which is the element that separates a professional sequence from a nuisance and measurably improves reply rates on the contacts who were never going to buy.
Day 90. A single re-engagement note tied to something that has actually changed — a new product, a specification revision, a relevant event date. One message, then the record goes quiet. Records that are never suppressed are the reason event follow-up is disliked by recipients, and one ignored record costs more credibility than ten that were never made.
Two rules that apply across the whole sequence. Every message needs a working unsubscribe that suppresses the record everywhere it exists, not just in the sending tool. And the sequencing should be recorded per contact with the timestamp and the channel, so that when somebody asks six months later whether this person was contacted, the answer is a lookup rather than a reconstruction.
