Integration details

Description

SendHQ is an email API and inbox for product teams and AI agents. This connector lets Claude work in your SendHQ workspace: read and search received and sent mail and threads, send email from your verified domains (single messages, batches, replies and attachments), manage drafts, hosted templates, labels and receiving addresses, add and verify domains and their DNS records, and investigate deliverability, bounces, complaints and suppressions. Tools that send real email or delete data are annotated as such, so you can require approval for them under Settings > Connectors > SendHQ. The connector uses its own API key, named after Claude, which you can delete under API Keys to disconnect. It cannot create or revoke API keys or change billing. Workspaces on the free integration trial can deliver only to the account email or AWS SES simulator addresses.
