Your sender configuration determines whose name appears in recipients’ inboxes, which email address you send from, and which service handles delivery. Getting this right matters for both brand consistency and email deliverability.Documentation Index

Why sender setup matters
When someone receives an email from you, the first thing they see is your From name and address. A professional, recognizable sender identity improves open rates and builds trust. On the deliverability side, sending from a properly authenticated domain (DKIM + SPF) dramatically reduces the chance of your emails landing in spam.The two sender options
| Option | Best for | Setup complexity |
|---|---|---|
| UPBEAT shared sender | Default. Zero-config. Good for getting started. | None — works out of the box |
| Bring your own Resend | Custom domain, full DKIM/SPF authentication, best deliverability | Medium — requires a Resend account, a verified domain, and DNS records |
Setting up Resend
Resend gives you full control over your sending domain with DKIM and SPF authentication. It’s the recommended option for any founder sending email at scale.Connect Resend in Integrations
Open Settings and scroll to the Integrations section, find the Resend card, and click Connect. You’ll be asked for your Resend API key, which you can find in your Resend dashboard.
Add your domain in Resend
In Resend’s dashboard, go to Domains and click Add Domain. Enter the domain you want to send from (e.g., yourdomain.com).
Add DNS records
Resend will show you two sets of DNS records to add: DKIM (a TXT record) and SPF (another TXT record). Add these to your domain’s DNS settings through your domain registrar (Namecheap, GoDaddy, Cloudflare, etc.).DNS changes can take up to 48 hours to propagate, though they’re often active within a few hours.
Verify your domain
Back in Resend’s dashboard, click Verify once you’ve added the DNS records. When Resend shows a green Verified status, your domain is ready to send.
Set your From name and address in UPBEAT OS
Open Settings and scroll to the Email sender section. Enter:
- From name — How you want to appear (e.g., “Steph from UPBEAT” or your company name)
- From address — A verified address on your domain (e.g., hello@yourdomain.com)
- Sending route — Select Resend
Using the UPBEAT shared sender
If you don’t connect Resend, UPBEAT OS sends through its shared Resend infrastructure. Your From name appears on the email and recipients see UPBEAT’s shared sending domain. This is fine for low-volume sends and getting started, but for serious email at scale, switch to Bring Your Own Resend so you control the domain reputation.What DKIM and SPF are
If you’re setting up Resend with a custom domain, you’ll need to add two DNS records:- SPF (Sender Policy Framework) — A DNS record that tells receiving mail servers which services are authorized to send email on behalf of your domain. Without it, your emails are more likely to be flagged as suspicious.
- DKIM (DomainKeys Identified Mail) — A cryptographic signature that verifies your email hasn’t been tampered with in transit. It’s the strongest signal of sender legitimacy for inbox providers like Gmail and Outlook.
Setting your From name and address
Regardless of which sender option you use, configure your From name and address in the Email sender section of Settings:- From name — What recipients see in the “From” field (your name, your brand name, or a combination)
- From address — The email address you’re sending from (must be on your verified Resend domain when using BYO Resend)
- Reply-to — Optional address replies should route to
