Use Mermail for a specific business goal, from researching prospects and writing outreach to setting up a support inbox for your brand. Each guide explains what you need, how to run the workflow, and what to check before you finish. ## Choose your workflow Find prospects with Apify, prepare personalized emails, and send reviewed outreach from your Mermail mailbox. Follow the Shopify-in-Australia demo. Set up branded support for an online store using shared website knowledge and signatures for selected mailboxes. ## Start with the right setup * **A mailbox:** [Create a mailbox](/guides/create-mailbox) and choose the [workspace](/concepts/workspaces) that owns the workflow. * **An assistant connection, when needed:** For workflows in an external AI assistant, [connect Mermail through MCP](/ai/mcp). The assistant's available tools depend on the connection and your permissions. * **Paid research, when needed:** [Set up Agent Wallet](/agent-wallet/get-started) before using a paid service. Customer Support website setup does not require the Apify purchase described in Sale Outreach. ## What to expect from a guide Use the example prompts as starting points. Replace the audience, sender, business details, and budget with your own requirements. Check the selected mailbox and any proposed external action before approving it. Research results, saved emails, and sent emails are separate outcomes. A paid research request does not send outreach, and preparing an email does not mean it has been sent. Each guide includes checks for its final result.
