MCA Inbox home

The desk

How hundreds of thousands of letters still find the inbox.

Ordinary sending tools last a few weeks on an MCA file. The domains burn, the shop starts over, and the same month repeats. MCA Inbox is the slower engine: separate names, human-scale volume, and copy that does not repeat.

Why the usual stack fails

MCA teaches filters faster than other lists.

Providers learn phrasing, domains, and send fingerprints. Shared IP pools and one-inbox blasts collapse once complaints climb. We do not bolt a slider onto that problem. The engine is the product.

  1. 01 — Fold

    The letters are written

    We slice your file by industry, state, and inbox type, then write a fresh note to each slice — in your voice, never the same letter twice.

  2. 02 — Warm

    The desk comes up slowly

    Dedicated domains and IPs, kept separate from every other desk, are brought up over weeks. Your house domain never sends a single cold note.

  3. 03 — Fly

    Mail goes out at human scale

    Volume is split across many inboxes, each at a human-scale daily send. Up to 10,000 emails a day, per brand, without one mailbox blasting.

  4. 04 — Land

    Placement is seed-tested

    We test inbox placement to major providers continuously. If it drops below 90% at full speed, those days are credited.

  5. 05 — File

    A complete application arrives

    The merchant opens your application portal, fills the funding form, and attaches statements. The file lands in your inbox or CRM, tagged to its batch.

What the desk reports

Two views you get every week.

The sending pool behind your brand, and what each batch produced, reported every week.

What we will not do

Mail from your house domain

Outreach uses dedicated sending names so a block cannot kill the inbox you run payroll from.

Call a click a win

A result is a completed application with statements, attributed to the batch it came from.

Keep a copy of your file

You own the list and the application portal. We will not resell names or send you to a lead vendor.

Ready to send

Bring the list. We handle the sending.

Inbox placement is seed-tested to major providers. If it drops below 90% after you are at full speed, those days are credited. How the promise works
