Fusion Mailers

Match and merge

The list you actually meant to send to.

The first deliverable is a count, not a file. Records are reconciled across sources before anything is counted. The delivered count and the approved count are the same number.

Phone formatting
Rendering numbers in a consistent international form, with the original retained.
File assembly
Records drawn together against those criteria, deduplicated, and checked for completeness.
Decay review
Identifying the records that have stopped being current, and how many of them there are.

Tell us what went wrong with the last file and we will work from there.
