Type your subject line and preview text below and see exactly how it looks across every major email client before you send. Say "adios" to truncated surprises.
The extension lets you check any subject line instantly. Open it and type, or just select text on any page and it auto-fills.
✓ Add to Chrome (it's free)I built this because I kept running into the same problem myself. Every time I wrote a campaign, I had no idea how the subject line would actually look until it was already in people's inboxes.
For some reason, the majority of email service providers still don't show you subject line truncation by default. You'd think this would be table stakes by now. It's not.
So I'd send myself test emails. Then check on my phone. Then desktop. Then a different app. "Hey mum, please check the email I sent to your Huawei and send me a screenshot"
When you send dozens of campaigns every month, that adds up to a lot of wasted time. Valuable time I could be spending doing literally anything else... like brewing myself a 4th cup of coffee.
