Talk to the SendStack team

We are a small team that answers its own email. Pick the channel that fits and we will get back to you.

Support

Questions about sending, deliverability, billing or your account. We aim to reply within one business day.

Higher volumes, dedicated IPs, managed sending or a custom plan. Tell us what you are building.

Prefer to chat? Message us on WhatsApp - handy for sending sender-ID documents or a quick question.

Most integration questions are answered in the API reference - endpoints, auth, webhooks and SDK snippets.
