EmailShield Reviews & Product Details

We send cold emails at volume and reuse the same lists roughly every 90 days. Even after cleaning those lists with tools like MillionVerifier and other legacy tools, our bounce rate was still too high—around 7–11%. We switched to EmailShield on the free tier, and bounces dropped to about 3%. The API is fast and straightforward to call, which matters because it’s part of our automated sending pipeline. The biggest improvement for us has been catch-all detection. EmailShield flags a lot more risky catch-all domains before we send. Review collected by and hosted on G2.com.

Early on, the CSV upload didn't accept files with more than one email field, which was annoying for how we structure our lists. We flagged it to support and they fixed it in under a day. Honestly this ended up highlighting a strength more than a weakness, their dev team is responsive and actually ships fixes fast. Review collected by and hosted on G2.com.

Catch-all handling has been the biggest difference for us. We clean B2B lead lists before every campaign, and with ZeroBounce a large share of addresses came back as “catch-all” with no clear answer, so we either had to send blind or discard them. EmailShield actually resolves most of those, and our bounce rate dropped from around 6% to under 1.5% on the same types of lists. Pricing is also noticeably lower per verification, which at our volume adds up quickly. Review collected by and hosted on G2.com.

We'd like a few more native integrations with CRMs so we could sync cleaned lists back automatically instead of exporting a CSV, and the dashboard could show a bit more history per list. Both are minor next to the accuracy difference. Review collected by and hosted on G2.com.

0.5 to 0.8% - that's where our bounce rate has sat since we moved over, and for a team that verifies every three days, that consistency is the whole product. Catch-all domains were the reason we left our last tool; here they come back with an actual answer. Results per address are granular enough that I know exactly what to do with each one.

Would rather have historical reporting in the dashboard. . I can see each job perfectly well, but comparing list quality month over month means exporting into a spreadsheet myself. Review collected by and hosted on G2.com.

Emailshield is the first verification tool in our experience that combines accurate Outlook verification with a fair pricing model. We're developing software for AgTech companies, and since our TAM isn't that big, it's crucial for us to be sure our outreach is set up perfectly. Using other verification tools led to sending emails to catch-all/non-existent emails even when the service claimed they were valid. We really like that Emailshield's UI provides fields such as unknown, disabled, and catch-all, so we're more confident that our emails won't land in fake inboxes. And the pay-as-you-go model works perfectly at our small verification scale Review collected by and hosted on G2.com.

We didn't find any downsides. It simply provides better performance for teams like us compared to other legacy tools Review collected by and hosted on G2.com.

Microsoft API check. Our buyers are IT directors, nearly all on M365, and our old tool said unknown for most of them. EmailShield confirms those. Bigger list, same bounces. Review collected by and hosted on G2.com.

No native Smartlead integration yet. Still exporting CSVs and uploading them by hand. Review collected by and hosted on G2.com.
