Transactional email, done properly

Email your users actually receive.

Nextsend is the independent transactional email platform from Nexthomelabs — a clean API, an SMTP relay, and deliverability tooling that treats your sender reputation like production infrastructure.

ProperOutbox accounts and sessions are separate from Nexthomelabs.

Everything between your code and the inbox

Transactional email API

One POST sends a message. Idempotency keys keep retries safe, and every send is tracked end to end.

SMTP relay

Point your existing apps at our SMTP endpoint with scoped credentials per environment.

Sending domains

Guided SPF, DKIM, and DMARC setup with live DNS health checks on every domain you add.

Analytics

Delivery, bounce, and complaint rates per domain, per stream, per day.

Event webhooks

Deliveries, bounces, and complaints pushed to your endpoints with signed payloads.

Reputation guardrails

Suppressions, blocklist monitoring, and DMARC reports keep your sender reputation intact.

Templates & logs

Design reusable templates and search full message logs whenever you need answers.

Scoped API keys

Production and test keys with per-project limits, rotated without downtime.

Pricing

Works from applications hosted anywhere

Nextsend is not tied to NexHost. Buy it by itself and send from any application, on any host, through the API or SMTP. It can also be included in selected Nexthomelabs bundles.

Nextsend or ProperInbox?

Nextsend

Automated application email: password resets, verification codes, receipts, order confirmations, alerts and delivery notifications — sent by your software through the API or SMTP.

ProperInbox

Human staff mailboxes such as info@, support@ and sales@ on your company domain, with webmail, IMAP and SMTP. Compare ProperInbox and Nextsend.

Must I host on NexHost to use Nextsend?
No. Nextsend works with applications hosted anywhere.
Can I buy Nextsend together with hosting and mailboxes?
Yes. Select a bundle on the Nexthomelabs pricing page and make one payment; every included product activates automatically.
Does NexHost Plus include transactional email?
Not by itself. Purchase Nextsend separately or choose a bundle that includes it.
Can I test before going production?
Yes. Start in the sandbox with test emails to verified recipients, then add a sending domain and go live.
