Pay as you grow • From $0.0002 per validation
Allegrow alternative
Looking for an Allegrow (allegrow.co) alternative? OrbiSearch resolves catch-all and SEG-protected emails on pay-as-you-go pricing from $0.0002 per validation. No $99 per month minimum, no annual contract, credits never expire, plus private dedicated infrastructure for high-volume customers.
Allegrow verification is subscription-only: $99 per month for 5,000 credits, then $8 per 1,000. OrbiSearch is a one-time credit pack from $30, and the credits never expire. Verify 100,000 emails for $103 instead of $859.
Both services return a definitive valid or invalid on catch-all and Secure Email Gateway domains instead of an unknown. With Allegrow, unlimited volume means Scale Plus at $1,340 per month billed annually. OrbiSearch has published packs all the way to 10 million emails. See our catch-all domains benchmark for what the data shows is actually resolvable.
OrbiSearch offers dedicated validation infrastructure on the 5M and 10M packs, with white glove data cleaning and quality monitoring. Allegrow does not offer an equivalent service.
We publish head-to-head numbers only when we have run a competitor through our own benchmark. Allegrow is not in it yet, so the figures below are each company's own published tests, not a side-by-side. Read how the OrbiSearch benchmark works.
