100k Global Ionos B2B Leads

I am assembling a master database of 100,000 fresh, accurate B2B contacts from companies whose corporate email is hosted on Ionos / 1&1.

Scope
• Worldwide coverage is fine—any country or region qualifies as long as the domain’s MX records clearly show Ionos / 1&1.
• I am not limiting the search to particular industries or job roles; breadth is welcome provided every record is genuinely tied to an Ionos-hosted domain.

Required data columns
1. Company name
2. Website / domain
3. Contact person’s full name
4. Job title
5. Corporate email address (no Gmail, Outlook etc.)
6. Country
7. Optional but appreciated: direct phone and LinkedIn URL
8. Proof of Ionos / 1&1 hosting (e.g., captured MX record or ISP flag)

Quality expectations
• 100 % unique records—no duplicates.
• Hard-bounced emails under 2 %.
• All entries supplied in CSV or Excel with UTF-8 encoding.

Acceptance criteria
– Minimum 100,000 rows that meet all “Required data columns”.
– Random sample of 1,000 records must pass ZeroBounce or NeverBounce at 98 %+ validity before final hand-off.

Timeline is flexible, yet let me know how long you need for collection and verification so we can agree on milestones.
