What this tool checks
Plus tailored recommendations on what to fix and how to improve.
Deliverability
SPF, DMARC, MX, DKIM, and reverse DNS — every record that decides whether your emails reach the inbox or land in spam.
Transport security
MTA-STS and TLS reporting, so encrypted email between servers can't be silently downgraded.
Brand in the inbox
BIMI and Verified Mark Certificate (VMC) — whether your logo shows next to your name in Gmail, Apple Mail, and Yahoo.
ESP detection
Which marketing ESP, transactional provider, and SMS tool your storefront uses — plus whether your tracking links run on a branded subdomain.
Signup form
Whether your homepage has a working signup form on desktop and mobile, above the fold, plus any email-capture popup.
Form quality
Bot protection, consent checkbox, privacy-policy link, signup incentive, and whether phone and email fields sit side by side.
Cost-saving opportunities
Klaviyo overspend patterns, manual segmentation work, SMS tools you could consolidate, and duplicate ESPs burning budget.
Recommendations
For every issue we find, you get a clear, prioritised fix — so you know exactly what to improve next.
