Instantly vs Leadspicker (2026)
The decision is what you own when you leave. Instantly sells the sending infrastructure as well as the software, and its agreement states in terms what that means: domains and mailboxes offered under labels suggesting purchase are provisioned, registered, owned and operated by the vendor under its own name and billing, the buyer acquires no ownership, no equitable interest and no right to transfer, port, migrate or take control of any of it, and on exit the vendor may disable, reclaim, repurpose or retire it. In cold email a warmed sending domain and the reputation attached to it are the asset that takes weeks to build, and it is precisely what a departing customer cannot take. All fees are non refundable and unused credits are forfeited on termination. Leadspicker runs the opposite position on the one thing it meters: separately purchased credits are stated to remain with the buyer until spent and explicitly not to be taken away on cancellation. One vendor's exit terms are drafted, deliberate and adverse. The other's are drafted, deliberate and favourable. Both are worth reading before signing.
- The regulatory drafting has to name the statutes. Instantly's agent terms cite the federal telephone statute with its implementing rule, the telemarketing sales rule, registry requirements, named state telephone solicitation acts, recording consent laws, a specific state artificial intelligence disclosure code section, biometric privacy laws and four further national regimes, with an anti spam policy incorporated and breach grounds for immediate closure.
- You want disclosure to be a control the customer cannot switch off. Every voice call must state the business identity, a contact number, that the voice is artificially generated and that the call is recorded, with the artificial identity line inserted by the platform and the buyer expressly forbidden from removing, suppressing or contradicting it.
- The removal apparatus should publish its own outcomes. Instantly's privacy record includes 2025 request statistics: two hundred and fifty three requests to know all complied with at a three day median, and five thousand two hundred and twenty nine opt out and deletion requests all complied with at a one day median, which nothing else in this index publishes.
- Prepaid value should survive cancellation. Separately purchased credits are stated to remain with the buyer until spent and explicitly not to be taken away on cancellation, against a counterpart whose credits are forfeited on termination and whose fees are non refundable and non cancellable with no proration of any kind.
- You want to choose the model and see the price before it runs. A picker exposes three named providers per action with the exact cost per row displayed, and two routes are published for removing the vendor from the model path entirely, by connecting your own provider key or driving the agent through the protocol server.
- The supplier chain should be a table rather than a claim. Six sources are named with the role each plays, a cached lead database, a first pass address finder, a fallback second, a validation service, a global telephone provider and a web search service, each marked as queried live or served from cache.

The short version of each
Instantly
Instantly is a cold email outreach platform operating as Foo Monk, LLC, combining unlimited connected sending accounts and a reciprocal warmup network with a stated 450 million contact database, verification, website visitor identification and a line of agents covering lead finding, email writing, reply handling and outbound voice, alongside its own provisioned sending infrastructure. The GTM Tech Index grades it D on exit and data portability, the sharpest exit position it holds, and for an architectural reason rather than a merely contractual one: the domains and mailboxes sold under labels suggesting purchase are owned and operated by the vendor, the buyer acquires no right to transfer or port them, and on exit the vendor may disable, reclaim or retire them.

Leadspicker
Leadspicker is a Czech prospecting platform combining autonomous discovery agents, a named enrichment waterfall and multichannel email and professional network sequencing in one product, with agents configured in plain language and a single credit currency defined as one euro cent. The GTM Tech Index grades it B on exit and data portability, and records the reason as a term drafted in the buyer's favour rather than a mere absence of a bad one: separately purchased credits are stated to remain with the buyer until spent and explicitly not to be taken away on cancellation, which is the inverse of the forfeiture recorded elsewhere in this index and is published where a buyer decides rather than buried in terms.

Common questions
Is Instantly better than Leadspicker?
What you own when you leave. Instantly's agreement states that the domains and mailboxes it sells are provisioned, registered, owned and operated by the vendor under its own name, that the buyer acquires no ownership and no right to transfer, port or migrate any of it, and that on exit the vendor may disable, reclaim or retire it. In cold email a warmed sending domain is the asset that takes weeks to build. Leadspicker states the opposite on the thing it meters: purchased credits remain with the buyer until spent and are explicitly not taken away on cancellation.
Do either name the AI models they use?
Both do and they name different things. Leadspicker names three model providers in its pricing table with a picker exposing the choice per action and the cost per row shown before anything runs, which the GTM Tech Index grades A. Instantly sells access to five major language models, names two of them on the plan card, names its voice technology sub processor with retention periods attached, and lets a buyer supply their own provider key, which the index grades B because no model version, inference location or accuracy rate is given.
Which one addresses outreach compliance?
Instantly, and by the widest margin in the index. Its agent terms name a federal telephone statute with its implementing rule cited by section, the telemarketing sales rule, registry requirements, individual state solicitation acts, recording consent laws, a specific state artificial intelligence disclosure provision, biometric privacy laws and four further national regimes. Two provisions go beyond naming: the voice agent may only call a person from whom prior express written consent has already been obtained, and calling any number from a purchased, rented, scraped or enriched list is prohibited outright. At Leadspicker no consent standard, unsubscribe mechanic or sending statute appears anywhere.
Where does the contact data come from?
Neither names a supplier for its own core database, and both publish more than most around it. Instantly enumerates source classes covering data compilers and consumer resellers, publicly available websites, its own customers and government sources, names the supplier behind its website visitor product outright, and publishes a live removal page with a fifteen business day commitment and 2025 request statistics. Leadspicker publishes six named sources as a table with the role each plays and whether it is queried live or served from cache, while saying nothing about the layer where its own agents gather directly.
How much do Instantly and Leadspicker cost?
Both publish completely and the index grades both A. Instantly prices three product lines separately with monthly allowances against each, add on rates published rather than quoted, per action consumption rates, sold infrastructure priced to the domain and mailbox, a stated no overage policy and credit expiry disclosed against its own interest. Leadspicker defines a credit as one euro cent so the credit figure and the money figure are the same number, publishes a price for every action, charges per delivered result so an unenriched row costs nothing, and states that purchased credits survive cancellation.
How does the GTM Tech Index grade Instantly and Leadspicker?
Both are graded on the same seventeen capability and compliance axes from public sources, at documented depths of sixteen and seventeen. The GTM Tech Index grades Instantly A on outreach compliance posture, data privacy posture, data licensing and provenance and commercial transparency, and B on autonomy, AI disclosure, platform terms, recipient disclosure, ecosystem, residency, deliverability and segment coverage, with a D on exit and data portability. Leadspicker takes A on AI disclosure, ecosystem and integration depth and commercial transparency, and B on operational evidence, data licensing, exit and segment coverage. The index publishes no composite score and declares no winner.

Instantly's warmup network deserves attention before anything else on this page, because it is a mechanism most competitors describe vaguely and this vendor documents. The notice states that a participant's name, address and signature contact details are shared with other participants, so the buyer's own sending identity becomes visible inside a pooled network of strangers, and pooled outreach success data is used to give other customers benchmarking.
What the network does functionally is manufacture engagement between participating mailboxes, which is signal creation rather than sending discipline, and it sits alongside pre warmed domains and mailboxes sold as a product and a sharding system that swaps a flagged sending address out immediately, treating a reputation penalty as something to route around rather than something to correct. The same vendor is unusually candid about what else it takes.
Its agreement states plainly that it is not responsible for how third party model providers handle inputs or outputs including their use in training, takes a perpetual and irrevocable licence to deidentified aggregated data with the right to make it publicly available, and defines performance data broadly enough to cover session recordings, mouse movement and keystrokes outside form fields. None of that is and all of it is drafted.
Leadspicker approaches the same question from the other end, publishing no training position of its own at all and offering instead two routes by which a buyer keeps content out of the vendor's model relationships entirely: connect your own provider key, or drive the same agent through the protocol server inside your own client software. One vendor tells you precisely what it takes. The other tells you how not to give it. Neither states whether customer content trains anything the vendor itself operates.
