Verifies addresses at the mail-server level by pinging each recipient's server, catching hard bounces before a campaign goes out.

Slower, human-paced query frequency is designed to reduce false positives compared with aggressive verification speeds.

Verification is batch-based: results are downloadable in 24 to 48 hours, so it cannot validate addresses in real time, such as at signup.

Uploaded lists remain on Pabbly's servers for up to 15 days by default, which may not satisfy teams that require immediate deletion.

Pay-as-you-go credit packs ($8 for 1,000 up to $2,000 for 1,000,000) never expire, so occasional senders avoid a recurring bill while high-volume senders drop to roughly $2 per 1,000 emails.

Duplicate addresses and "unknown" results are never charged, so you don't pay for unverifiable or repeated entries in your lists.

Verification credits require a minimum purchase of 1,000 ($8), so teams that only verify a handful of addresses occasionally may find a full platform is more than they need.

Real-time API verification requires developer work to integrate, so non-technical teams can't set it up instantly the way they can with bulk uploads.
