B2B email append
Email appending services for contacts you can't email yet
You have names and companies but no email addresses. Our email appending services match each contact, find the business email and verify it, so your existing list becomes a list you can send to.
- Matched by name and company
- Verified before delivery
- Thousands to millions of records
| Contact | Email found | Status |
|---|---|---|
| Laura Chen, Brightline Dental | l.chen@b•••.com | Verified |
| Marcus Hill, Hill & Rowe Law | mhill@h•••.com | Verified |
| Priya Nair, Coastal Freight | priya@c•••.com | Verified |
| Tom Reed, Old Mill Supply | No valid match | Removed |
How email appending works
Six stages, grouped into four steps you will see in your project updates.
- 1
Database analysis
We check which records have enough to match on: a full name plus a company name or website.
- 2
Data matching
Each contact is matched against trusted business sources to confirm the person still works at the company.
- 3
Email append and verification
The business email is added, then verified at the mailbox level. Invalid and risky results are dropped.
- 4
Quality check and delivery
A final review, then the file comes back with your original columns plus email and verification status.
Our email appending services
B2B email appending
Business emails for decision-makers already in your lead database, so reps can reach them directly.
Business email append
Professional addresses added to company and contact records for sales, partner and vendor outreach.
Phone and email append
Both channels added in one pass when you want to call and email the same contacts.
CRM email append
Missing emails written back to your CRM records, mapped to your existing contact IDs.
Email database enrichment
New emails appended while your existing addresses are re-verified, so the whole list is current.
B2C email appending
Consumer email addresses added to customer files where you have a lawful basis to contact them.
What you need to send us
Email append accuracy depends on what you start with. A full name and a company website gives the best match rate. A name and company name works well too. A first name alone does not.
Send your file as it is. We clean and standardize the input before matching, and tell you how many records are matchable before you pay for the full run.
- First and last name
- Company name or website domain
- Optional: job title, city, LinkedIn URL
- Any format: CSV, Excel or CRM export
Email appending vs buying a new list
| Question | Email appending | New email list |
|---|---|---|
| Starting point | Contacts you already know | A new target audience |
| Best for | Customers, event leads, old CRM records | Reaching people you have never met |
| Contacts | Yours, completed | New, researched for you |
| Next step | Send us the file | Send us your filters |
What comes back from our email appending services
Your file keeps its original columns. We add these alongside them.
| Column | What it shows |
|---|---|
| Business email | The appended work address for the contact. |
| Verification status | Valid or catch-all, so you decide what to send to. |
| Match result | Matched, or left empty when we could not match with confidence. |
| Record ID | Your CRM ID, when you send one, so the file re-imports cleanly. |
Email appending services add email addresses to contact records that do not have one. The provider matches each person by name and company against trusted data sources, finds their current business email and verifies it before adding it to your file.
B2B email appending focuses on business addresses for people at companies, such as decision-makers in your CRM or a trade show list. It uses company and job data to match, so results are work emails, not personal ones.
Every appended address is verified before delivery, and records we cannot match with confidence are left empty. Match rates depend on your input. Records with a full name and company domain match best.
Yes. Send a CRM export with record IDs and we return the file mapped to those IDs, ready to re-import so new emails land on the right contacts without creating duplicates.
Appending business emails for B2B outreach is legal in the US when you follow CAN-SPAM. For B2C appends, and in regions covered by GDPR, you need a lawful basis to contact the person. We can advise on what applies to your list.
We quote per file, based on record count and input quality. You see the matchable count before paying for the full run.
An email append adds email addresses only. A data append can also add phones, addresses, titles and company details.
