Here is where 1Lookup wins against LeadPost, and where LeadPost still wins.

Questions

People ask these questions before they switch from LeadPost.

What is the best LeadPost alternative?

If you want direct mail and paid-social retargeting on the same leads, or consumer leads, LeadPost is built for that: LeadPost sells B2C plans up to 4,500 leads a month and retargets by email, social, display and mail. If you want the individual person as data, by API, webhook or CSV, at 5 credits per person on a balance that also pays for phone, email and IP lookups, 1Lookup's Website Visitor ID is the alternative. Website Visitor ID requires approval. Start the 7-day free trial, then send the short application inside your account: we review each website before we switch on visitor identification.

How much does LeadPost cost?

Separate B2B and B2C lead capture plans, each with a monthly cap: B2B from 250 to 1,000 leads a month and B2C from 750 to 4,500. A 14-day free trial with no card: up to 100 B2B leads or 200 B2C leads. Checked October 2026 on leadpost.com.

How much does 1Lookup charge for an identified visitor?

5 credits for each identified person, and nothing for a visitor who is not identified. Starter ($99 a month) covers up to 4,000 identified people at $0.02475 each, Growth ($299 a month) covers up to 17,000 identified people at $0.0176 each, Professional ($799 a month) covers up to 50,000 identified people at $0.016 each and Enterprise ($1,999 a month) covers up to 200,000 identified people at $0.01 each. Credits come from a plan that also pays for every other 1Lookup product, and unused subscription credits roll over for up to 3 months.

Is 1Lookup cheaper than LeadPost?

On month-to-month billing 1Lookup costs less at 1 to 1,000 people a month. LeadPost never costs less than a 1Lookup plan in its published range. At 250 identified people a month, 1Lookup Starter costs $99 and LeadPost B2B Standard costs $199. At 500 identified people a month, 1Lookup Starter costs $99 and LeadPost B2B Advanced costs $349.

Does LeadPost identify people or companies?

People: LeadPost captures visitors as leads, on B2B plans with location, email, industry and job-title filters and on separate B2C plans.

Which visitors does 1Lookup identify?

Website Visitor ID identifies visitors worldwide outside Europe: every country except the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland. A visitor it cannot identify, wherever they are, costs no credits, because only identified people are billed.

What comes back for each identified person?

Identified people come back by API, by webhook or in a CSV file, each with a name, a work email, a LinkedIn profile URL, a job title and a company, and a phone number with its do-not-call flag for about 1 in 4 people.

Do unused credits carry over?

1Lookup subscription credits roll over for up to 3 months, so a quiet month does not waste a plan.

How do I switch from LeadPost to 1Lookup?

Add one script to the pages where you want visitors identified, and pick where the people go: an API, a webhook or a CSV. LeadPost also retargets the leads it captures, so keep your retargeting where it is and feed it 1Lookup's records by webhook or CSV. Run LeadPost and Website Visitor ID side by side for a month and compare the named people you get before you cancel anything.

Is LeadPost worth it in 2026?

Yes, if you want consumer and business lead capture with retargeting by email, paid social, display and direct mail, and up to 1,000 B2B or 4,500 B2C leads a month covers you. If you want a named person with a work email for each identified visitor, from $99 a month for 4,000 identified people, compare 1Lookup.
