Email marketing for consultants is a long game with a short list. You are not selling to 10,000 people; you are staying visible to 400 who might need you in eighteen months. That makes the tool choice easy and the content choice hard. systeme.io holds the list free to 2,000 contacts with the call booking in the same account. The harder question, what to write so a director remembers you at renewal time, is below.

What to send
- A point of view. The argument you would make in a meeting, written in 300 words. Not a summary of industry news.
- A short case note. The situation, what you changed, what it produced. Anonymised if the client requires it, specific either way.
- A useful artefact. The checklist, the one-page framework, the questions you ask in a first session. These get forwarded internally, which is how consulting leads arrive.
- An occasional availability note. Two or three times a year: what you are taking on next quarter.
A nurture sequence that books calls
Day 0: deliver the lead magnet, usually a diagnostic or a framework. Day 3: the point of view behind it, and why most teams get it wrong. Day 8: a case note showing it applied. Day 15: an offer of a short call, framed as a conversation rather than a pitch. Then monthly.
