Guaranteed Inbox Email Delivery

I’m launching a promotional push for my service and need every message to reach the primary inbox. I have a vetted list of business-owner contacts (roughly 5,000 – 20,000 addresses) and the single goal is to promote my product or service—no newsletters, no events, just one clear offer.

Whether you prefer a fully manual send or an automated campaign makes no difference to me; what matters is achieving near-perfect inbox placement and being able to prove it with solid post-send analytics. Please be prepared to handle authentication (SPF, DKIM, DMARC), warming if needed, and any list-hygiene steps required to maximise deliverability.

Deliverables
• Campaign sent to the full list with documented 100 % (or as close as technically possible) inbox delivery
• Detailed report showing sends, opens, clicks, bounces and complaints
• Brief summary of any content or list improvements you recommend before or after the send

In your proposal, tell me which platform or SMTP solution you’ll use (e.g., SendGrid, Mailgun, Amazon SES, custom), the process you follow to secure inbox placement, and examples of similar volumes you’ve handled successfully. If you can meet the guarantee, I’m ready to move fast.
