sending.ac Review — Honest Pros, Cons & Pricing (2026)

Category: Cold email infrastructure and campaign setup platform

Also known as: sendingac, sending.ac.

Overview

sending.ac is a cold email infrastructure platform that streamlines email outreach campaign setup with automated DNS and inbox provisioning. The platform handles the technical setup work that can slow down teams launching new cold email campaigns, including domain configuration and inbox creation. Automated SPF, DKIM, and DMARC setup is part of the provisioning process, which is standard for any serious cold email infrastructure provider. The platform targets teams that want to get campaigns running quickly without manual infrastructure work. If you're researching sending.ac pricing and reviews, look for specifics on inbox quality, provider type (Google Workspace vs Outlook 365), and whether pre warmed accounts are available. Dedicated cold email infrastructure providers like Puzzle Inbox offer pre warmed inboxes across both Google Workspace and Microsoft 365 with transparent pricing, which provides a useful benchmark for comparing what sending.ac delivers per inbox.
