DiscoLike vs Allegrow

DiscoLike finds the contacts and verifies their emails in real time, with catch-all resolution included. For new prospecting, compare sourcing and checking upstream data with paying for validated contacts delivered.

Get contacts verified in real time, with catch-all resolution
Allegrow answers: is this contact's address valid? It returns a conclusive answer on many catch-all domains where other verifiers give up, but you bring the address and each contact counts against your plan. If the answer is invalid, you still have no one to email.
DiscoLike finds the contact and verifies the email in real time, with catch-all resolution included. Describe who you want to reach at your target companies. Only validated contacts with an email reach your results. You pay for delivered contacts plus 1 record per company that delivers a validated contact when you search without your own company list. This avoids buying upstream contact data and then paying to check unusable addresses.
To check addresses you already have, use Allegrow. To find contacts with email verification in real time and catch-all resolution included, use DiscoLike.
Allegrow pricing compared
Allegrow verifies up to 1,000 addresses free. Starter is $99/mo for 5,000 contacts ($19.80 per 1,000), with add-on credits at $8 per 1,000. Scale Plus is $1,340/mo billed annually for unlimited verification, with API use capped at 1 million requests a month. Data providers can buy a custom API plan.
DiscoLike has Pay as you go and subscriptions at $99 to $1,599/mo in credits. Validated contacts cost $25/1,000 on Pay as you go, $17.50 on Starter, $15 on Pro, $12.50 on Team, and $10 on Company and Enterprise. Searching without your own company list adds 1 record per company that delivers a validated contact, at the plan rate. Validated and Validated (catch-all resolved) cost the same. Every delivery is billed, including repeats.
Catch-all domains
Allegrow describes mailbox-level checks on catch-all domains and secure email gateways, using its own signals to distinguish valid from invalid addresses. Its public wording separates domain-level catch-all detection from assessing a particular mailbox. These are Allegrow's published capability claims, not an independent comparison of accuracy.
A catch-all domain accepts mail for any address, so acceptance by the domain alone does not prove a mailbox exists. Validated (catch-all resolved) means the mailbox was verified in real time. The domain accepts all mail; we resolved the catch-all and confirmed this address exists. Another verifier may report catch-all or unknown; you do not need to re-check it. Contacts appear only after validation. DiscoLike runs its own email engine rather than reselling a verification API.
Where Allegrow wins
CRM hygiene and deliverability for enterprise teams. Allegrow verifies contacts inside HubSpot, Outreach, and Salesloft with workflow rules, flags spam traps, disposables, and inactive or non-primary mailboxes, and adds domain health monitoring and SPF, DKIM, and DMARC checks. It is SOC 2 certified with SSO. If your job is keeping an existing database clean at high volume, the unlimited plan is built for it and DiscoLike is not.
