Common questions.

Do you connect to apps like online stores or CRMs?

Flashmail does not have a marketplace of ready-made app connectors. You can connect any system that can call an API, and bring website signups in with the tracking snippet and signup forms.

Can I use my own sending server?

Bringing your own sending server depends on your plan. See Pricing for what each plan includes.

Where is the API documentation?

Your API token, the endpoint and a quick reference are in your account under Account → API.
