The 4 best FullEnrich alternatives in 2026 start with 1Lookup, which returns a verified work email in the same request, not by a webhook that typically takes 30 to 90 seconds.

These are the reasons teams look beyond FullEnrich.

• No standalone verification: the documented endpoint set is enrich, reverse email lookup, people search, company search, lookup, credit balance and key check. There is no endpoint that takes an email or phone you already hold and returns a validity verdict, no phone validation, no line type or HLR data and no IP product. Verification runs only on data FullEnrich itself found
• The enrichment API is asynchronous by design. You POST a batch, get an ID back, and results arrive by webhook or polling, which the docs put at "typically 30-90 seconds per contact". That rules out inline use in a form or a checkout
• Default rate limit is 60 API calls per minute across all endpoints, with a default queue of 100 concurrent enrichments per workspace. Higher limits and priority queue are an Enterprise line item, "set based on your volume in the commercial agreement"
• Mobile numbers cost 10 credits each, so phone-heavy workloads move up the ladder fast: their own worked example puts 1,000 contacts enriched with email plus mobile at 5,800 to 7,800 credits
• Subscription-only, with no true pay-as-you-go: you buy a monthly or annual volume tier upfront. Running out mid-cycle is resolved by renewing early or upgrading a tier, and there is no published overage rate
• Credits expire after the rollover window, 3 months monthly, 12 months annual and 6 months for a one-time purchase, and credits in a deleted workspace are forfeited with no refund
• Redistribution is contractually restricted: the client may not sell, resell, assign, transfer, distribute or licence the enriched data to third parties without a specific agreement, and a reseller agreement is an Enterprise item
• Data quality is contractually the providers' responsibility, not FullEnrich's: "The Client acknowledges that the quality of Enriched Data depends on the Providers and communicated Client Data and that FullEnrich is not responsible for it"
• The CRM story is thinner than the logos suggest. On the plan comparison table HubSpot push is live but "Enrich Contacts Already In HubSpot" and "FullEnrich Inside HubSpot" are both marked Soon, Salesforce's "Push Contacts & Companies" and "Enrich Contacts Already In Salesforce" are marked Soon, and Pipedrive, Folk, Zendesk, Smartlead, Instantly, Lemlist, HeyReach, Gong, Outreach and Salesloft are all listed as Soon on the integrations page
• Two different data postures under one brand, which matters for a compliance review: the trust page states "Waterfall Enrichment does not use a database and does not create one either", but the People and Company Search product does run a FullEnrich-built database sourced from two data providers, and their privacy policy registers the company as "a data broker under Texas law"

This table compares all 4 on the same criteria.

Product	Email	Phone	IP	Starting price	Free option
1Lookup				$99/mo for 20,000 credits ($4.95 per 1,000, down to $2.00 on Enterprise)	Free single lookups via the online tools at 1lookup.io/tools, no account required
Prospeo				$49/user/month for 2,000 credits (Starter, monthly), or $441/user/year for 24,000 credits (all credits released on the purchase date). 2,000 credits buys up to 2,000 verified emails or 200 verified mobiles, since a mobile costs 10 credits	Free plan, $0, 100 credits per month with no time limit: people and company search on 28 of the 41 filters, 3 intent topics, a 25-row selection cap for export, Chrome extension, MCP server, CSV export and 5 AI Lookalike searches. No CSV enrichment and no integrations. Prospeo's two published sources disagree on API access: the pricing page's plan-comparison table marks the public API not included on Free, while the help centre publishes Free rate limits of 1/second, 20/minute and 50/day
Anymail Finder				$29/month for 400 credits, their page's own rate being $0.073 a credit; a credit is one verified person email, so that is $72.50 per 1,000 verified emails at the entry tier. The cheapest yearly commitment is $228 for 4,800 credits ($0.048 a credit)	100 free credits on signup, usable "across single search, bulk, and the API". A card must be added: "Sign up, verify your card, and your credits land instantly. Your card is only verified, not charged", and "you're only charged if you choose a plan". Their acceptable use policy qualifies it: free credits are "subject to our automated fraud detection systems; there is no guarantee that customers will receive free credits"
Lusha				$49.90/mo for Starter with 400 credits/mo (= up to 400 email reveals or 40 phone reveals); $37.45/mo billed annually ($449.10/yr for 4,800 credits/yr)	Free plan at $0 with up to 40 credits/month (= up to 40 email reveals or 4 phone reveals at current credit costs); includes the browser extension and CRM integrations. Free-plan credits reset monthly and do not carry over.

Prices verified from each vendor’s public pricing page as of August 2026. Pricing models differ (subscriptions, pay-as-you-go credits, per-lookup metering), so compare at your real monthly volume; the full per-vendor volume tables are on each linked comparison page.

This is who should choose each one.

• 1Lookup: Best for a synchronous answer instead of a webhook.
• Prospeo: Best for building the list and revealing it in one place.
• Anymail Finder: Best for high-volume email finding with credits that do not expire.
• Lusha: Best browser extension for rep-driven contact grabbing.

This is how much work a switch takes.

Run the same list through both for a week and compare match counts on your own contacts. Then weigh the integration change: an asynchronous batch plus webhook becomes a synchronous call, which usually deletes a queue, a callback handler and a retry policy from your codebase.

These are the questions people ask about FullEnrich alternatives.
