Promotional Bulk Email Dispatch

I need help executing a one-time promotional blast to an existing list of roughly 1 k–10 k contacts. The list is cleaned, fully opted-in, and ready to upload; what I lack is the infrastructure and expertise to ensure the messages hit inboxes, not spam folders.

Here’s what I’m looking for:
• You supply or set up the delivery platform (Mailwizz, SendGrid, Amazon SES, or a comparable SMTP solution).
• I give you the HTML creative and subject line; you manage any technical tweaks—DKIM, SPF, domain warm-up if needed—to maximize deliverability.
• After launch, I receive a concise report covering sends, opens, clicks, bounces, and complaints.

If you already have warmed IPs and can demonstrate recent success with promotional campaigns of a similar size, that’s a strong plus. Turnaround is flexible but ideally within a week of project start.
