Many tools like DigitalOcean, Pulseway etc do not support webhooks as alert channels. In this case, you can choose to create an Email integration with Spike.sh to get incidents and relevant alerts.
Select Email from our list of integrations and use the uniquely generated email address on any tool of your choice. The emails received are managed by us for your integration. There is no inbox :)
From the header > click Add integration and select email, give it an appropriate name create the integration.
Copy the Email from the integration page.
You can choose to send an email to your unique email address to test if an incident gets created.
