Temporary High-Deliverability Email Sender

My acquisition firm relies on cold outreach—brand acquisition offers, technology-licensing deals, and wider partnership inquiries—but too many messages from my own domain and even our Gmail accounts are landing in spam. While I begin the slow process of warming a fresh address, I need an inbox with a rock-solid sender reputation that I can tap into right away. Here’s what I’m after: • An existing mailbox (any mainstream provider or custom domain) that already enjoys excellent inbox placement and passes common spam-filter checks. • The ability for me to send up to a few dozen personalized emails per month from that address while my new domain reputation grows. • Basic setup help—forwarding, aliasing, or SMTP credentials—so the workflow feels seamless on my side. • A short “handover” guide so I can replicate your deliverability practices on my own warmed domain once it is ready. I’m comfortable drafting and scheduling the messages myself; your main contribution is the trusted sender address plus any technical pointers that keep delivery rates high (SPF, DKIM, consistent sending volume, etc.). If you have analytics that demonstrate current inbox performance, please mention them in your proposal. I’m ready to move quickly—let me know how soon your address could be live and any safeguards you’d like in place to protect its reputation during our collaboration.
