The problem

Good referral relationships die in a contacts spreadsheet.

You meet the right people, but the actual introduction — the email that connects them — keeps slipping. When it does happen, it reads like a form letter, because you're writing the same intro for the fifth time this month.

The SwitchBoard121 way

Pick one partner, connect them to everyone who's a fit.

SwitchBoard121 keeps your partners organized, assembles each two-way intro from their own words, and sends it from your real mailbox in a single click — strengthening the relationship on both sides, and replies land in your inbox, not a third-party platform.

How it works

From two contacts to a sent introduction, in under a minute.

See the full walkthrough

1. Add your partners

Build a simple directory of the people you send business to and receive it from.

2. Connect one to many

Pick one partner, then select everyone they should meet — all at once.

3. It sends as you

We drop in each partner's own paragraph and send it from your own mailbox, signature included.

Why it's different

Not a mass-mail tool. Not a CRM. Just better introductions.

Sent from you, not us

No third-party sender domain. Every intro carries your real address and reputation.

Your signature, automatically

Every intro carries your real signature — no copy-paste, no missing logo.

No more contact spreadsheet

One organized place for every referral partner, instead of a stale spreadsheet.

Full send history, always

Every introduction you've sent, searchable, so nothing falls through.

Your credentials are never stored in plaintext.

Microsoft mailboxes connect through delegated OAuth — we never see your password. SMTP credentials are sealed with encryption before they ever touch our database.

Simple, transparent pricing

$10/month per user, billed annually at $120/year.
