For startups & SaaS
Announce, onboard and grow — with an API from day one
Verify signups, send product updates and newsletters from your domain, and connect everything to your stack through a straightforward REST API.
Sound familiar?
Fake and mistyped signups
Free trials attract disposable addresses and typos that never convert and hurt deliverability.
Tools priced for bigger companies
Early-stage teams need to pay for usage, not for a tier.
Engineering time
You want a clean API, not a week of integration work.
How InboxRoads helps
REST API
Add contacts, submit verification jobs and read campaign results with bearer-token authentication.
Signup verification
Send new signups to the verify endpoint and keep disposable and invalid addresses out of your list.
Product announcements
Launch emails and changelog newsletters with merge tags and fallbacks.
Authenticated domain
SPF, DKIM and DMARC generated for your domain, so launches look as professional as your product.
Usage-based
Credits scale with your sends, not with a pricing tier.

One balance, two jobs
1 credit = 1 email verification or 1 email send.

50,000 credits can be used for:

InboxRoads is designed for marketing campaigns and newsletters. Keep password resets and receipts in your application’s transactional email service.
