Inbox-Ready Bulk Email Setup

I need a dependable bulk-sending environment that pushes every personalised message straight into the primary inbox—even at high volumes. When the form asked about the campaign’s main purpose I simply typed “hi”; the real priority is deliverability, not labels. The platform is still open: Mailchimp, SendGrid, Constant Contact, or an independent SMTP stack all work for me, provided they pass the spam-filter gauntlet.

My existing HTML templates look good but they clearly need a deliverability-focused tune-up. Help me adjust the layout, inline styling, wording and tracking so they trigger fewer filters and render flawlessly across devices.

Deliverables & acceptance criteria
• Fully configured sending infrastructure with SPF, DKIM and DMARC authenticated and verified.
• IP/domain warm-up plan implemented and documented.
• Test batch of 1,000 personalised emails achieves at least a 90 % inbox-placement rate on Gmail, Outlook and Yahoo (validated via Mail-Tester, Gmail Postmaster Tools or similar).
• Refined, responsive HTML templates plus matching plain-text versions supplied.
• Step-by-step guide showing exactly how I can repeat campaigns on my own.

Let me know which stack you propose, your timeline and any data you need from me to get started.
