SendGrid integration
Send quotes, invoices, dunning notices and portal emails from Bunny through your own SendGrid account, on your own domain and reputation.
What the integration does
Your domain, your reputation
Billing email goes out from your company domain rather than a shared platform sender, which matters for both trust and deliverability.
Everything transactional
Quote notifications, invoices, payment receipts, dunning notices and portal invitations all route through SendGrid.
Your existing deliverability setup
SPF, DKIM and domain authentication are configured once in SendGrid and apply to Bunny's mail automatically.
One key to configure
An API key and a sender address is the whole setup.
An invoice email that lands in spam is an invoice that gets paid late. A dunning notice from an unfamiliar sender is one a finance team ignores. Billing email is the highest-stakes mail most SaaS companies send, and it is usually the mail they think about last.
Routing it through your own SendGrid account puts it on your domain, under your authentication records, and inside the deliverability monitoring your team already runs.
What to set up first
Domain authentication in SendGrid, before anything else. Once SPF and DKIM are in place and the sender address is verified, adding the API key to Bunny is a one-minute job and every billing email from then on goes out as you.

Keep the stack you have
Bunny sits between your CRM, your tax engine, your payment processor and your ledger — so quoting, subscriptions, usage and invoicing share one system of record without anyone migrating off the tools they already use.
