Resend Setup

Resend powers transactional emails in ClientFlo — workspace invitations, password resets, invoice notifications, and contract signing links. The free tier includes 3,000 emails per month.

💡

Free tier: 3,000 emails/month, 100 emails/day — enough for most freelancers and small teams. No credit card required.

Step-by-Step Guide

Follow this walkthrough to verify your domain and create an API key:

Configuration Values

After setup, collect these values:

Variable	Source
`RESEND_API_KEY`	Resend Dashboard → API Keys (required)
`BREVO_API_KEY`	Brevo Dashboard → API Keys (fallback, optional)

ℹ️

Brevo fallback: Brevo offers 300 free emails/day. If you prefer Brevo over Resend, set BREVO_API_KEY and leave RESEND_API_KEY empty. ClientFlo falls back automatically.

Next, configure Google Calendar.
