Prospeo

The 5 best Prospeo alternatives in 2026 start with 1Lookup, which has no per-seat price, and its unused credits roll over for 3 months.

1Lookup is the best Prospeo alternative when you already know who you are looking up: a verified work email from a LinkedIn profile URL per call, with no seats, no charge on a miss, and unused credits that roll over for 3 months. FullEnrich and Anymail Finder are the closest finder swaps, Lusha covers the browser motion, and ZoomInfo covers search at enterprise depth.

A verified work email from a LinkedIn profile URL in the same request, with no charge on a miss
No seats, and unused monthly credits roll over for 3 months
Phone, email and IP validation on the same credits

Prices verified August 2026 on each vendor’s own pricing page.

These are the reasons teams look beyond Prospeo.

It is not a validation service: there is no standalone email verification, no phone validation, no line type or HLR data and no IP product, and no way to pass in an address or number you already hold and pay to check it. Verification only ever arrives attached to a find
Nothing rolls over anywhere. Monthly, yearly and add-on credits all expire at the cycle end, a yearly plan's unused balance dies at the annual renewal, and switching billing period wipes add-on credits on the spot
Price and credits are per seat: a 3-seat Pro plan is three times $249/month for 45,000 pooled credits, all seats must sit on the same tier, and removing a seat destroys that seat's credits immediately
Subscription only, with no pay-as-you-go and no per-call billing. The cheapest paid entry is $49/month, and Credit Add-ons require an active paid plan
A mobile costs 10 credits against the same pool as emails, so a plan's headline credit count shrinks tenfold for phone work: Starter's 2,000 credits is 200 mobiles
API throughput below the top tier is thin, and search over the API is metered: Starter allows 2,000 enrich calls and 1,000 search calls a day, Growth 5,000 and 4,000, and each search request that returns results costs 1 credit for up to 25 rows with no contact data
No contractual SLA and no SOC 2 or ISO 27001 claim on any Prospeo page: the terms state Prospeo does "not promise outcomes, accuracy, coverage, or uninterrupted service", while their Data Enrichment API page markets "99.99% uptime"
The output licence is restrictive: no resale or redistribution, no using outputs to build a competing database or model, no caching beyond what the plan allows, and no making "safe-to-call", "safe-to-email" or accuracy claims to third parties based on Prospeo data

1Lookup leads the shortlist, followed by the closest swaps.

1. 1LookupTop pick, our product

Best when you already know who you are looking up

Pick 1Lookup when the search is not the part you need: you hold the profile URLs and want a verified work email per call, with no seat to buy and nothing expiring at the end of the cycle.

Starting price: $99/mo for 20,000 credits ($4.95 per 1,000, down to $2.00 on Enterprise)

2. FullEnrich

Best find rate, by routing one request through many vendors

Pick FullEnrich when coverage is the whole point and you would rather buy one waterfall than sign a contract with each of the vendors inside it.

Starting price: $29/month for 500 credits ($0.058 a credit) on the Pro monthly ladder, which is up to 500 verified work emails found or 50 mobile numbers found. Billed yearly the entry rung is $312/year for 6,000 credits ($0.052 a credit). The pricing page's own slider defaults one rung up, at 1,000 credits a month for $55
Free option: Free trial: "50 credits to start", "No credit card", and extra credits for inviting team members. Full Pro feature access on it, including the API, MCP server, CRM integrations and bulk CSV. 50 credits is 50 work emails, or 5 mobile numbers at 10 credits each
The catch: 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

3. Anymail Finder

Best for high-volume email finding with credits that do not expire

Pick Anymail Finder when email finding is the whole job, and rollover with no cap while you stay subscribed, no published rate limits, and unlimited seats matter more than breadth.

Starting price: $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)
Free option: 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"
The catch: Email only. No phone number validation, no line type, carrier or HLR data, no IP intelligence and no address data: the whole catalogue is finding and verifying work email

4. Lusha

Best browser extension for rep-driven contact grabbing

Pick Lusha when your team's core motion is pulling contact details from LinkedIn profiles one at a time while browsing, and a simple monthly credit tier beats API flexibility.

Starting price: $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 option: 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.
The catch: Phone numbers cost 10 credits vs 1 credit per email (per the live pricing page), so plan allowances effectively shrink 10x for phone-centric workflows - Starter's 400 credits buy only 40 phone numbers (~$1.25 each)

5. ZoomInfo

Best enterprise depth: US coverage, intent, and org charts

Pick ZoomInfo when you are an enterprise revenue team with a procurement cycle, and platform breadth plus the deepest US database outweigh self-serve pricing.

Starting price: Core platform: not publicly listed - every contract is sales-quoted. Self-serve GTM AI by ZoomInfo: pay-as-you-go top-ups starting at $20; data credits list at $0.35/record ($0.10/credit limited-time launch promo, auto-applied to your first 5,000), AI credits $0.05/credit flat.
Free option: ZoomInfo Lite: permanent free tier, no credit card, no expiration - 10 credits/mo (25/mo with Community Edition contribution), advanced contact/company search, contact exports, Chrome extension (ReachOut), WebSights Lite (up to 10 visitor reveals/day), email sending, HubSpot CRM integration. GTM AI: 100 data + 500 AI credits free at signup, free search/lookup/find-similar, and free-tier MCP, API, and CLI access (5 req/sec, 5 apps).
The catch: Core platform pricing is not published anywhere: ZoomInfo's own pricing guide states no dollar amounts are listed because pricing is consumption-based and varies by organization; paid plans are "billed annually, not monthly" with "no standard monthly billing option"

Lusha: Best browser extension for rep-driven contact grabbing.

This is how much work a switch takes.

Start by separating the two jobs Prospeo does for you. If you use the 41-filter search to build lists, that capability has to be replaced deliberately, not assumed. If you only use the reveal, a profile-URL endpoint is a drop-in. Either way, credits do not roll over anywhere on Prospeo, so time the move to the end of a cycle rather than paying for a balance you will abandon, and remember removing a seat destroys its credits on the spot.

These are the questions people ask about Prospeo alternatives.

What is the best Prospeo alternative?

If you already have the people and only need contact details, 1Lookup takes a profile URL and returns a verified work email per lookup, with no per-seat charge, no charge on a miss, and no separate credit pool. If the searchable database is what you use, ZoomInfo and FullEnrich cover that ground and Lusha covers the browser motion.

Is there a Prospeo alternative that is not priced per seat?

Yes. Prospeo prices both the plan and its credits per user, so a three-seat team pays three plan prices, and removing a seat destroys that seat's credits. FullEnrich and Anymail Finder both publish unlimited users on every plan, and 1Lookup bills per lookup with no seat concept at all. The table above records what each vendor publishes.

Do Prospeo credits roll over?

No. Prospeo's help centre states unused credits expire at the end of each billing cycle on every plan, yearly plans release all twelve months of credits upfront and lose the unused balance at renewal, and switching billing period destroys add-on credits immediately. Expiry rules are the sharpest difference between the vendors on this shortlist.

Can Prospeo verify an email I already have?

No. Prospeo publishes no standalone verification, no phone validation and no IP product: verification only ever arrives attached to a find. If you need to check addresses, numbers or IPs you already hold, that is a separate tool, or an API that does both jobs on one credit balance.
