Email Appending Services

Fill the gaps in your CRM. We match your customer records against our permission-based database and return verified business emails.

Overview

What this service does

Most customer databases are only partially usable for email marketing — records collected at trade shows, from sales calls or over years of operations often lack a current business email. Email appending fixes that: we match your records against our verified, permission-based database and return accurate email addresses, ready for campaigns.

How it works

A four-step proven process

Data analysis

We review your file, standardise formats and identify the records eligible for matching.

Multi-key matching

Records are matched on name, company and domain signals using deterministic and fuzzy logic.

Verification

Every appended email passes syntax, domain and mailbox-level deliverability checks.

Secure delivery

Your enriched file is returned securely, with match-rate reporting and full field mapping.

Benefits

FAQ

Frequently asked questions

How long does email appending services take?

Standard projects complete in 2–4 business days depending on file size. Large enterprise files are scoped up front with a committed timeline, and rush processing is available when a campaign deadline is close.

How is pricing structured?

Pricing is volume-based and, wherever the service produces matches or corrections, you pay only for successful results — matched emails, corrected records, validated addresses. You'll receive a fixed quote after a free audit of a sample file, with no obligation.

Is my customer data safe with you?

Yes. Files are transferred over encrypted channels, processed in access-controlled environments, and deleted after project completion per our retention policy. We're happy to sign an NDA or data-processing agreement before you send anything.

What file formats do you accept and return?

We accept CSV, Excel, and direct exports from all major CRMs. Your enriched or cleaned file is returned in the same structure you sent, with new fields clearly appended, so re-importing takes minutes rather than a mapping project.

Do you work with small files or is there a minimum?

There's no hard minimum — startups send us a few thousand records, enterprises send millions. The free audit tells you exactly what the service will change in your file before you commit to anything.
