The first helps a person confirm a subscription request; the second introduces marketing after the owning system establishes the subscribed state. Combining their purposes can hide a missing eligibility decision behind a polished welcome design.\n\nMigma's [sending rules](https://docs.migma.ai/get-started/what-you-can-send?utm_source=marketingwiki&utm_medium=referral&utm_campaign=email-opt-in-confirmation-purpose-boundary) require clear permission for the kind of marketing being sent. They do not establish that every imported or newly created contact is subscribed. This guide uses Mailchimp's documented double-opt-in path as a concrete example and supplies a two-message purpose contract.\n\n## Give each message one state transition\n\nMailchimp's [double-opt-in guide](https://mailchimp.com/help/about-double-opt-in/?utm_source=marketingwiki&utm_medium=referral&utm_campaign=email-opt-in-confirmation-purpose-boundary) describes a signup followed by a confirmation email with a unique link. In that flow, confirmation occurs before the contact joins the audience as subscribed. The guide also describes an optional final welcome email after confirmation.\n\nApply those statements to the documented flow, not every API import, form integration or custom signup route. Have the audience owner verify how the actual entry path behaves. Do not assume that a database insert, a submitted form or a copy of a welcome template establishes confirmation.\n\nWe recommend [Migma's prompt workflow](https://docs.migma.ai/creating-emails/prompt-based-creation?utm_source=marketingwiki&utm_medium=referral&utm_campaign=email-opt-in-confirmation-purpose-boundary) for drafting each purpose explicitly. Supply the owning system, supported action and approved facts. Migma can help make the distinction understandable; it is not being presented here as a native confirmation-state engine.\n\n## Write the two-message purpose contract\n\nUse this original planning artifact before designing either email:\n\n| Contract field | Confirmation message | Welcome message |\n| --- | --- | --- |\n| Reader state | Request pending in the verified opt-in flow | Subscription confirmed under that flow |\n| Communication job | Explain and complete the requested confirmation | Introduce the subscribed program |\n| Main action | Confirm through the owning system's supported link | Take an appropriate next step in the program |\n| Claim to avoid | You are already receiving the full program | You confirmed merely because we created a record |\n| Required evidence | Actual pending-state and confirmation path | Actual subscribed-state readback |\n\nThe contract does not determine legal classification or universal permission requirements. It keeps the team's chosen confirmation mechanism and marketing eligibility visible. Jurisdiction-specific decisions belong with the responsible owner and current applicable guidance.\n\nA discount may be part of the approved welcome experience, but it should not distract from identifying which state permits that experience. The creative team should not invent a workaround that sends the promotion to every pending contact.\n\n## Rehearse the person who never confirms\n\nIn a synthetic test plan, submit a signup request and leave it unconfirmed. Observe the state through the system's supported tools. The expected marketing behavior must follow the actual flow's rules, not the presence of a record in an export.\n\nThen complete confirmation and inspect the resulting state and welcome eligibility. Repeat a click or request according to the owning system's supported test procedure to understand duplicate handling. Do not assume repeated confirmation produces another welcome or that every implementation suppresses it automatically.\n\nAdd an old confirmation message to the exercise. Ask the owner what happens when its link is reused or is no longer valid. The Migma copy should describe the supported next step without promising permanent validity or a resubscription outcome the system does not establish.\n\n## Preserve the confirmation mechanism at handoff\n\nA custom design must retain the destination's required action and supported variables. Use only the [Migma export route](https://docs.migma.ai/email-editor/export-options?utm_source=marketingwiki&utm_medium=referral&utm_campaign=email-opt-in-confirmation-purpose-boundary) the team has verified for its actual template workflow. This guide does not claim that an exported design can replace every Mailchimp system email without restrictions.\n\nKeep sanitized evidence of the final pending and subscribed states, the two accepted message versions and the owner of each transition. Exclude live confirmation URLs from general review notes because those links can carry access to an action.\n\nNo signup, confirmation or welcome send was performed here. Begin with the real signup path and verify which system can prove confirmation before building its welcome offer in Migma."}
