Introducing Smarter Email Capture: We Fix Typos So You Don't Lose Subscribers
Every email address your popups and forms capture is a potential customer relationship , but not every address that gets submitted is actually usable. A shopper rushing through checkout, typing on a phone keyboard, or just not paying close attention can easily fat-finger their email domain: an extra letter tacked onto ".com," a dropped letter in "yaho" a duplicated "comcom" or "gmailgmail" at the end. The intent to sign up was real. The email address, unfortunately, is not.
That gap between "submitted" and "deliverable" has always been a quiet tax on email capture programs, and until now, brands have had no way to close it at the point of entry.
The hidden cost of a mistyped domain
A misspelled top-level domain (TLD) or email provider might look like a small thing, but it adds up fast when it's happening across thousands of popup submissions:
Every bad address is an acquisition cost with no return. You paid for that click, that discount incentive, that moment of attention — and the welcome email, the coupon code, the abandoned cart reminder all bounce into the void.
Bounces damage sender reputation. Email service providers watch bounce rates closely. A steady trickle of undeliverable addresses from your capture forms can quietly erode inbox placement for every subscriber on your list, not just the mistyped ones.
Subscriber counts get inflated with dead weight. A list that looks bigger isn't better if a meaningful share of it can never be reached. It skews engagement metrics and makes list health harder to diagnose.
The typos are common, and they cluster. Think "gmail.comcom," "gmail.comr," "gmail.comx," "icloud.co," "yahoo.comp," or a jumbled "hotmial.com" instead of "hotmail.com." These aren't rare edge cases — they're some of the most frequent errors we see across email capture forms, and they were previously invisible until a bounce report showed up days later.
What's new: automatic email domain correction
Smarter Email Capture fixes this in real time, right where the address is collected. When a shopper types an email with a misspelled domain or TLD, Justuno automatically detects and corrects it before the submission is saved — turning "gmail.comcom" into "gmail.com," "icloud.co" into "icloud.com," and "hotmial.com" into "hotmail.com," among many other common variations.
There's no popup interrupting the shopper, no error message asking them to try again, and no extra step added to the flow. The correction happens quietly in the background, and the address that lands in your list is the one that actually reaches an inbox.
The impact: +2% more deliverable subscribers
Across the accounts where this is live, correcting misspelled domains is translating into 2% more deliverable subscribers — email addresses that are valid, reachable, and actually capable of receiving your welcome series, promotions, and lifecycle campaigns. That's 2% more of your capture volume turning into a list you can actually market to, not a bounce statistic.
Works everywhere, with nothing to set up
Smarter Email Capture is built into the Justuno platform itself, which means it works automatically across every email capture experience you're already running — popups, embeds, banners, and beyond. There's no toggle to find, no new integration to configure, and no workflow to rebuild. If you're capturing emails with Justuno today, you're already benefiting from cleaner data going forward.
Cleaner data. Stronger connections. Better results. That's the whole idea behind Smarter Email Capture — and it's live now, working quietly in the background of every form on your site.
