you can diagnose any cold email in 30 seconds flat.

this prompt runs your email through the 4-Checkpoint Pre-Send Evaluation i use with every customer at Premium Inboxes. paste it into ChatGPT or Claude and you'll know exactly what's broken before you hit send.

When to use this: before you send any cold email. every time.

I'm going to paste a cold email below. Analyse it against these 4 checkpoints and give me a score out of 10 for each, plus specific fixes.

CHECKPOINT 1 — AUTHENTICATION READINESS
- Does this email contain any spam trigger words? (free, guaranteed, limited time, act now, exclusive offer)
- Does it include links in the first email? (this is a spam trigger)
- Would this pass a spam filter scan based on language alone?

CHECKPOINT 2 — TRUST SIGNALS
- Does it establish credibility within the first 2 sentences?
- Is there a proof point or social proof element?
- Does it feel like a real person wrote it, or does it read like a marketing template?

CHECKPOINT 3 — BEHAVIOURAL ANALYSIS
- Is this email under 80 words? (optimal for cold outreach)
- Does it have exactly ONE call to action?
- Is the CTA low-friction? (soft question, not "book a call now")

CHECKPOINT 4 — IDENTITY VALIDATION
- Does the sender come across as a real person with context?
- Is there personalisation that proves this isn't mass-sent?
- Would the recipient believe this was written specifically for them?

For each checkpoint, give me:
- Score (1-10)
- What's working
- What needs to change (be specific, rewrite the problem sections)

Here's my email:

Pro tip: if you score below 6 on any checkpoint, fix that section before you send anything. i've seen emails with perfect copy still land in spam because they failed checkpoint 1 alone. the copy is the last thing that matters if your foundations are broken.
