I need a Mailchimp specialist to take my existing CSV list and configure a brand-new account capable of reliably sending about 100,000 transactional emails every day. The list is already cleaned on my side; what I lack is the technical groundwork that guarantees high deliverability and friction-free scaling. Your work will start with importing and organising the CSV, tagging customers for easy segmentation, and setting up authentication records (SPF, DKIM, DMARC) under my domain so Mailchimp recognises us as a trusted sender. From there I want a dedicated IP (or the most appropriate sending solution within Mailchimp Transactional), an initial warm-up schedule, bounce and complaint management, and detailed tracking so I can see open, click and delivery metrics in real time. Because these are transactional messages—order confirmations, shipping updates and the like—each email must render perfectly across common clients. I’ll provide copy; I’m counting on you for responsive template creation, merge tags and any API hooks that automate the send. By the time we wrap up, I should be able to: • press “send” (or trigger via API) on 100k messages without throttling issues • pass all major deliverability tests (Mail-Tester 9+/10, Google Postmaster healthy, no spam-folder placement) • view clear analytics dashboards and suppression lists inside Mailchimp If you have a proven track record scaling Mailchimp Transactional or Mandrill to this volume, let’s talk.
