1Lookup vs MailVeri

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

1Lookup

$99/mo 7 day free trial

One API for checking phone numbers, emails and IP addresses before they reach your dialer, sequencer or ATS, with contact enrichment and B2B data on the same credits. Plans start at $99/mo for 20,000 checks with a 7-day free trial, so it suits teams verifying in volume rather than a few lists a month.

Where 1Lookup fits

  • Agencies running texting or calling campaigns that need to scrub numbers for line type and DNC
  • Teams verifying emails and phones in bulk before loading them into an ATS or sequencer
  • Developers who want validation and enrichment behind one API key
  • Claude users who want to verify contacts from a chat

MailVeri

$9/10k credits Free trial

Pay as you go bulk email verifier for recruiters and outbound teams cleaning candidate or lead lists before a send. Credits never expire, 10,000 checks cost $9 and 100,000 cost $59, and signup includes 1,000 free credits with no card. It also has a REST API and an official MCP server for AI assistants.

Where MailVeri fits

  • Recruiters cleaning sourced candidate emails before a cold sequence
  • Agencies verifying Apollo, Clay or LinkedIn exports in bulk
  • Teams that send in bursts and do not want a monthly verification plan
  • Builders who want email checks inside Claude, Cursor, n8n or Make

Where they pull apart

1Lookup

Stands out: Phone checks are the strength: line type, carrier and DNC status come from FCC and carrier data refreshed daily, so recruiters can drop landlines and do-not-call numbers before a texting or calling campaign. Email, IP and enrichment lookups share the same balance, unused credits roll over for 3 months, and an MCP server lets Claude run checks directly.

Watch out: There is no free plan or pay-as-you-go pack; the cheapest option is a $99/mo subscription, which is a lot if you only verify a few hundred emails. Enrichment gets expensive fast at 10 to 75 credits a lookup. It is an API and dashboard product with no recruiting workflow, and the MCP server covers only validation, not enrichment.

Not the right fit for

  • Recruiters verifying a few hundred emails a month (a pay-per-credit verifier costs less)
  • Buyers who want a free plan
  • Teams looking for a sourcing database or outreach tool

MailVeri

Stands out: Price per check is among the lowest published in the category: $9 for 10,000 and $299 for 1,000,000, against $39 for 10,000 at MillionVerifier, with no subscription and credits that never expire. Only successful verifications use a credit, and an official MCP server lets Claude, Cursor or Codex verify single emails or whole batches from chat.

Watch out: It is a young brand with no Capterra or G2 profile yet, and the accuracy figure on its site is the vendor's own claim, so test it on a list whose bounce rate you already know before cleaning a large one. Purchases are final with no refunds, and the MCP server runs on your own machine through uv rather than as a hosted endpoint, so setup needs a terminal.

Not the right fit for

  • Buyers who want an established vendor with independent review history
  • Teams that need a hosted MCP endpoint with OAuth sign in
  • Anyone expecting a refund on unused credits
