Two decades’ expertise
Email appending is the process of adding verified email addresses to contact records that don’t have them. If you have a customer or prospect file with names and postal addresses — but empty or outdated email fields — an email append matches those records against verified email databases and returns deliverable addresses. It’s the fastest way to activate email as a channel for a list you already own, without starting from scratch or buying an entirely new list.
The value is in completeness and deliverability: a record with a valid email is worth far more than one you can only reach by mail. ProMarketing Leads matches your file against verified, permission-aware email data and returns clean, appended records — with a free match estimate and transparent pricing before you order.

Typically a file with names and postal addresses (business or consumer). The more complete your input records, the higher the match rate. Your data is handled securely and used only to perform the append.
Match rates vary by list quality, age, and type. We run a free match estimate against your actual file first, so you see how many records we can append — and the price — before you commit.
We match against verified email sources and screen for deliverability, but no append guarantees 100% inbox placement. Following email best practices and a proper warm-up improves results.
Appending is legal, but you remain responsible for CAN-SPAM compliance — including honoring opt-outs and sending only appropriate commercial email. We recommend a permission-conscious re-engagement approach for newly appended contacts.
Yes. We offer phone and cell append alongside email append, so you can complete your records across multiple channels from one partner. See our cell phone append service.
