The challenge

Sendora''s users kept asking for mailboxes inside the product instead of going to a third party, signing up, provisioning, then importing back. Building it in-house meant a multi-quarter project — domain registrar integrations, Google/Microsoft API work, deliverability tooling, warmup, support load. The CEO wanted the revenue line without the engineering bill.

Why they chose Icemail

The whitelabel + API combination meant Sendora could ship a fully branded "Sendora Mailboxes" product in weeks, not quarters, and keep 100% of the customer relationship and pricing.

The solution

Sendora wired Icemail''s API into their onboarding flow so any user could spin up domains and mailboxes from inside the product. The whitelabel layer kept everything under the Sendora brand — no Icemail logo, no external redirects. Billing rolled into their existing Stripe subscription.

The results

Shipped "Sendora Mailboxes" in 6 weeks (vs. an estimated 9-month internal build)
41% of paying users provisioned at least one mailbox in the first 60 days
$38,000 in new MRR attributable to the launch
Support tickets related to deliverability dropped 27% (customers stopped self-managing on flaky providers)

"We added a real infrastructure product to our roadmap and shipped it before our next board meeting. That''s never happened before." — Adrian Vale, CEO, Sendora

What''s next: Building a usage-based pricing tier on top of the mailbox product and exposing it through Sendora''s public API.
