Apollo vs Allegrow
Choosing between Apollo and Allegrow usually comes down to how each one deals with the addresses your list actually struggles with. Apollo is a per-seat sales platform with a large contact database and bundled verification. Allegrow is a catch-all verifier with sender reputation and inbox placement tooling attached. Below we walk through how they price, what they do with catch-all addresses, and how accurate each claims to be, and we show where Giggal.ai lands on the same list so you have a third number to weigh.

How Apollo and Allegrow handle catch-all
Apollo markets a seven-step process that distinguishes valid from invalid on catch-all at 91%. Allegrow resolves catch-all addresses to valid or invalid through a signal-based process rather than SMTP probing, and names Mimecast and Proofpoint. Catch-all domains accept mail for every name, so a normal check cannot tell a real mailbox from a dead one, and this is usually where a list quietly loses good contacts.
How Giggal.ai handles catch-all. Giggal.ai resolves catch-all addresses to a real deliverable or undeliverable result at 1.5 credits in a run, or 2 standalone.
Apollo vs Allegrow pricing
Apollo is priced per user seat, with verification bundled rather than sold by volume. Allegrow is sold by monthly plan, from $139/mo for 10,000 verifications a month. Both numbers come straight from each vendor's own pricing, so put them next to the volume you send each month.
