"How often should I check in?" assumes there's one right answer waiting to be found — a magic number of days that works for everyone in your book. There isn't. An active retainer client, a project you wrapped up six months ago, and a prospect who told you "not now" in March all need a completely different rhythm, and using the same cadence for all three either annoys the people you're closest to or lets the people you're losing go cold.
The useful question isn't "how often," singular. It's "how often, for this relationship, given where it actually stands."
Match the cadence to the relationship, not the calendar
Three relationship types cover most of a consulting book, and each has a different natural rhythm:
- Active retainer or project client: Check in at least every 2 weeks, even during a week where nothing is due. Silence from you during an active engagement reads as disengagement, not efficiency.
- Dormant past client (engagement ended, relationship didn't):Every 6–8 weeks. Frequent enough that you're top of mind when their next need comes up, infrequent enough that you're not manufacturing reasons to talk.
- Prospect who said "not now":Tie the interval to what they actually told you — if they said "check back after budget season," that's your date, not a generic 90 days. If they gave no timeline, default to quarterly.
The pattern underneath all three: the closer and more active the relationship, the shorter the interval — and the interval should shrink automatically as a relationship gets closer to a decision point, like a renewal or a stated follow-up date.
A worked example
Client A — active retainer: Monthly SEO retainer, $3,000/mo. Last real conversation was 12 days ago. No check-in needed yet — inside the 2-week window.
Client B — dormant past client: Wrapped a rebrand project 5 months ago. Last contact was a thank-you email 7 weeks ago. Due for a check-in now — this is exactly the 6–8 week window where a message keeps you top of mind before they forget you were ever the rebrand person.
Prospect C — said "not now":Told you in May they'd revisit after their fiscal year starts in September. It's currently early August. No check-in yet — reaching out now, a month before the date they gave you, would look like you weren't listening.
Same portfolio, three correct answers to "should I check in this week?" — none of which is visible unless you're tracking last-contact date and context per relationship, not just a flat list of names.
What a check-in should actually contain
"Just checking in!" is the single lowest-value message you can send — it asks the other person to do the work of finding a reason to reply. A check-in that actually lands does one of three things:
- Brings something specific. An article relevant to their industry, a result from work you did together, a change in their market you noticed.
- Asks a real question.Not "how are things?" but "did the Q3 reorg end up changing your reporting structure?" — something that shows you remember the actual state of their business.
- States a reason for reaching out now."You mentioned September — wanted to get ahead of your planning before it starts" gives them a frame for the message instead of making them guess why you showed up.
Any of these takes the same two minutes to write as "checking in!" The difference is entirely in whether it gives the other person something to respond to.
Getting the cadence right depends on knowing, at a glance, who's in which bucket and how long it's actually been — which is the same tracking gap covered in why consultants lose clients to neglect, applied here to timing instead of the underlying problem.
