# Modulify runs its outreachon OpenEmail.

Modulify builds a demo website for a business before it writes to them. OpenEmail sends the preview, tracks what happens to it and reports every delivery event back to Modulify's sales pipeline.

libs/openemail/DispatchEmail.ts

```
const client = new OpenEmail({  apiKey: env.OPEN_EMAIL_API_KEY,  timeoutMs: 30_000,  maxRetries: 2,}) const sent = await client.emails.send({  from: sender.name ? { email: sender.address, name: sender.name } : sender.address,  to: payload.to,  subject: payload.subject,  html: payload.html,  headers: payload.headers,  tracking: { opens: true, clicks: true },})
```

Every outreach email goes out with open and click tracking and unsubscribe headers. What happens next comes back on a signed webhook.

What runs through it

## What Modulify runs on OpenEmail.

- Site previews Sent once the team approves a prospect, with a link to the demo site built for them.
- Lead invitations Approved leads get an invitation to claim the site that was made for them.
- Offer reminders A note before a claim offer runs out, and another once it has.
- Open and click tracking Every outreach email is tracked, so the team can see who opened a preview and who clicked through.
- One-click unsubscribe Invitations carry List-Unsubscribe headers, which mail apps show as an unsubscribe button.
- Signed delivery events Each event arrives on a webhook that Modulify verifies before it changes anything.

How it was built

## How Modulify put it together.

1. 01
   
   Send from its own domains
   
   Modulify verified its brand domains on OpenEmail and sends from a hello@ address on each.
2. 02
   
   One sender per person
   
   Each recipient is matched to a single sender address, so a prospect always hears from the same one.
3. 03
   
   Send with tracking on
   
   Outreach goes out through the SDK's emails.send, with opens and clicks tracked and unsubscribe headers set.
4. 04
   
   Feed events into the pipeline
   
   Delivery events update each prospect. A bounce retires the invitation, and a complaint marks the lead as unsubscribed.
