Plan a price increase without losing the clients you want

Help me plan and communicate a price increase. You structure the rollout; the amount is my decision.

Current pricing: <what and how much>
New pricing I've decided on: <the new number(s) and when it starts>
My clients: <for each: name or type, what they pay, how long they've been with me, how I'd feel if they left>
Why I'm raising prices (the honest reasons): <costs, demand, scope creep, my time is worth more now>
What I've added or improved in the last year: <list>

Produce:
1. Client segments: who gets the increase first, who gets a grace period, who gets grandfathered for a while, and why for each.
2. A rollout calendar: who hears when, with dates.
3. The announcement message for existing clients, under 150 words: direct, no apology, no over-explaining, one line on what they get, the date, and how to talk to me about it.
4. A shorter version for new inquiries.
5. Three likely pushbacks with a calm two-sentence response each, including when to hold and when a middle option makes sense.
6. What I do if a client I want to keep says no.

No manipulative framing. No fake deadlines. Plain, respectful, firm.
