Thanks so much! really appreciate you taking the time to share it. Glad to hear the verifier is helping with both deliverability and accuracy that’s exactly what we built it for. Bulk + real-time was a big focus for us, so it’s great to see it working well for your use case. If there’s anything you’d love to see improved or added, I’m all ears. Thanks again for the support.

Sparkle.io is a lifesaver for small teams because it stops you from drowning in five different subscriptions just to send a few cold emails. It’s super straightforward, handles the technical "warm-up" stuff for you, and actually keeps your messages out of the spam folder without needing a dedicated IT person.

Thank you for the kind words! this is exactly why we built Sparkle.io. We know how frustrating it is for small teams to juggle multiple tools just to run outbound, so it means a lot to hear that Sparkle is helping simplify that process. Making email deliverability and warm-up effortless is something we’re constantly working to improve. Appreciate you taking the time to share this!
