Customer success how-to

How to write customer retention emails with Claude.

Retention emails are higher-leverage than acquisition emails because the audience already pays you. Most B2B teams underinvest because the per-segment customization is hard to scale. AI changes that. Here are the 3 sequence types and the prompts.

The 3 sequence types

When to use each

1. Renewal nurture (60-90 days before renewal). Reinforce value before the decision moment.

2. Expansion outreach. Trigger when usage signals warrant additional product.

3. Win-back. Targeted re-engagement for churned customers.

The renewal nurture prompt

Sequence 1

Build a 60-day renewal nurture sequence for [CUSTOMER NAME].

Customer plan: [TIER]
Renewal date: [DATE]
Their original use case (from sales): [SHORT]
Their usage pattern: [HEAVY / MODERATE / LOW USE]
Their last 6 months of engagement: [SUMMARY]
Key wins they achieved: [LIST]
Key friction they experienced: [LIST IF KNOWN]

3-touch sequence over 60 days:

- Day -60: ROI reminder — specific numbers showing what they got
- Day -30: Strategic check-in — what we could do together next year
- Day -7: Renewal confirmation + any negotiation flag

For each email:
- Subject line (specific, not "Your renewal is coming up")
- Body (150-200 words)
- Single CTA per email
- Personal tone — this is a relationship, not a campaign

The arc moves from "remember what you got" to "here is what is next" to "let us make this easy."
The win-back prompt

Sequence 3

Build a win-back sequence for a customer who churned [N MONTHS AGO].

Why they churned (stated reason): [REASON]
Why they REALLY churned (your honest assessment): [HONEST]
What has changed about our product since they left: [LIST]
What has changed about their business that we know of: [LIST IF KNOWN]

3-touch sequence over 60 days:

- Touch 1: "We have changed" — honest reference to the original reason, specific changes we have made
- Touch 2: Insight piece — relevant content with no pitch
- Touch 3: Specific offer — low-friction re-engagement

For each email:
- Acknowledge the past honestly (do not pretend they were not a customer)
- Lead with what changed, not what they should buy again
- Offer 1 specific easy next step (audit, call, free trial of a new module)
- Max 150 words

Voice: humble, specific, not pushy. They left for a reason. Earn the second chance.
