Tag your SDR team on this one.
If they've ever said 'the copy is fine, nobody's replying', they're probably right. It's usually the domain sending it, not the words.

Why "personalization at scale" quietly fails without deliverability behind it:
You can merge-tag a 10k list perfectly. If half of it lands in spam, nobody reads the personalization.
Fix the inbox first, then the copy.

One of our beta testers ran placement testing before a 10k-email send and caught a spam-trigger phrase before it went out.
That's the whole point โ catch it before, not after.
Building Sendbox. Happy to get into it in the comments.
Bad addresses quietly wreck your sender score.Bad placement wrecks your replies.

You pay for the tool, you own the fallout when your emails go to spam.

3 subject-line patterns that get flagged by spam filters before your prospect ever sees them:
1. Fake urgency ("Act now," "Last chance")
2. Symbol stuffing (emojis, ALL CAPS, !!!)
3. Broken personalization tokens ({first_name} failing)

One spammer tanks your warmed-up domain with them.
Sendbox gives every domain its own dedicated IP. Your reputation โ not shared with strangers.

Your cold emails are "sent."
They're just not being seen.
Spam folder โ inbox. And most outbound teams don't find out until pipeline dries up.
We built Sendbox to fix that.
