Bring Resend, SendGrid, Mailgun, or Amazon SES.
SendCanvas keeps campaigns and contacts in your app while your provider handles delivery. You supply the account, credentials, sending domain, and usage fees.
Provider credentials stay server-side.
Connections are verified before storage, encrypted at rest in local-installation mode, and never returned to the browser.
Resend
Connect a verified sending account for test and provider-preview delivery.
Twilio SendGrid
Use a scoped API key and ingest signed delivery events.
Mailgun
Configure a sending domain and region, then normalize signed events.
Amazon SES
Use region-scoped IAM credentials, a verified identity, quotas, and SNS events.
Cost calculator
See what owning your email stack could cost.
Pick your current platform, audience size, sending frequency, and delivery provider. Then compare the first year—including the $297 source purchase—with the ongoing cost after year one.
Interactive cost estimator
Build your email cost model
Transparent assumptions. Change contacts, send frequency, provider, and infrastructure instead of relying on a single headline number.
Ownership comparison. SendCanvas includes a one-time source purchase; vendor subscriptions continue every year.
Cost is not feature parity. SendCanvas is a prelaunch beta and still needs implementation before multi-user production sending.
Ownership model
SendCanvas is source code—not a hosted subscription.
Hosted tools are more mature and managed for you. SendCanvas is for buyers who want the application code and will own deployment. This compares pricing and ownership—not feature parity.

Estimates checked August 31, 2026 against published US monthly pricing: ActiveCampaign, Mailchimp, HighLevel, LC Email, Resend, SendGrid, Mailgun, and Amazon SES. Taxes, promotions, overages, add-ons, data transfer, dedicated IPs, implementation, and maintenance can change actual cost.

Questions before you buy
Ask AaronWhat exactly am I buying?+
The current downloadable SendCanvas prelaunch beta source and setup docs. You deploy and customize it; DevLaunch does not host it for you.
Can I send to my full list today?+
No. It is for local evaluation, customization, authoring, planning, and safe provider-preview tests. Multi-user production sending and distributed delivery still require integration work.
Which providers are supported?+
The code includes adapters for Resend, Twilio SendGrid, Mailgun, and Amazon SES.
What else do I need?+
You provide hosting, database, authentication, storage, a sending domain, provider credentials, quotas, monitoring, and provider usage fees.
Can I rebrand it?+
Yes. Core branding is configuration-driven, and deeper changes can be made in the source.
Do I control my audience and templates?+
They live in your installation. You are responsible for backups, privacy, consent, security, and lawful permission-based sending.
What is the refund policy?+
All sales are final. The complete digital source package is delivered immediately, so review the beta boundary and requirements before purchasing.
