Giggalai

Cold email lists rot faster than most senders admit — half the "risky" addresses are actually real mailboxes behind catch-all domains, and half the "valid" addresses are role accounts that will torch your deliverability the first time you send. Giggal.ai is a verification tool built specifically for the edge cases everyone else labels as "unknown" and skips.

What Giggal actually does

Giggal.ai runs email addresses through checks that catch-all and SEG-protected mailboxes usually defeat, then hands back a per-address deliverability score so you can decide what to send and what to drop.

• Identify real mailboxes behind catch-all and accept-all domains

• Verify addresses protected by Proofpoint, Mimecast, and Barracuda

• Upload files with up to 50,000 email addresses at once

• Return verification results in real time for faster list cleaning

• Score each address for deliverability alongside its valid/invalid status

• Flag disposable emails, role accounts, blacklist hits, invalid domains, and rejected mailboxes

The features that matter

The catch-all verification is the differentiator. Most verifiers give up when the domain accepts every email at the SMTP layer and label the address "risky" — Giggal actually probes further and comes back with a real answer. If your outbound list skews toward mid-market and enterprise (where catch-all domains are the norm), the recovered contacts alone can pay back the tool.

The SEG detection is the second lift. Addresses behind Proofpoint, Mimecast, and Barracuda are the ones most cold-email tools quietly flag as unverifiable — Giggal handles them, which matters if you are pitching security-conscious buyers.

How it fits in your stack

Giggal doesn't replace your ESP or your CRM. It sits between the list you export from HubSpot, Mailchimp, or ActiveCampaign and the campaign you're about to send — a scrubbing step that decides which addresses make it to the send queue. It can also be triggered by a Zapier or ChatGPT-driven workflow if you want the check to run automatically.

Who it's built for

Cold outreach teams whose lists lean heavily on catch-all business domains, agencies running lead-gen for B2B clients, and RevOps teams cleaning a stale CRM before a re-engagement blast. Solo founders can get value here too — one bad send to a stale list can drop a fresh domain into a spam folder and it is expensive to undo.

Giggal is worth it if catch-all and SEG-protected addresses show up on more than half of your list — otherwise a generic verifier will do the job.
