[Compare suitable agencies](https://internationalgrowthindex.com/services/email-marketing/#agencies) ## When this scope fits Use this scope for an audience with a documented basis for contact and a clear lifecycle. If list origin is uncertain, resolve eligibility before uploading it or planning campaigns. ## Questions that expose the scope - Who maintains suppression and unsubscribe rules? - Which lifecycle triggers and exclusions are tested? - How are campaign and automated-flow results separated? ## Agencies to consider An editorial selection based on explicit published service descriptions.

A service publication confirms the offer, not a delivered project; request a relevant case before committing. ## Prepare your brief List provenance, segments, consent records, sending domain, templates, product feed and purchase events. A sending-platform subscription, database acquisition and legal review are separate responsibilities. [CRM integration](https://internationalgrowthindex.com/services/crm-integration/) [Marketing analytics](https://internationalgrowthindex.com/services/marketing-analytics/) [Compare proposals fairly](https://internationalgrowthindex.com/guides/compare-agency-proposals/) ## Questions and answers Can open rate be the acceptance criterion? Use implementation checks and business-relevant actions too. A single engagement metric does not describe the quality of a lifecycle program. Who owns the sending domain? Document ownership and delegated permissions, and retain authentication and suppression settings when changing vendors. ## Source material - [Primary source: support.google.com / 81126 ↗](https://support.google.com/mail/answer/81126) Reviewed 11 September 2026.
