AutoInbox

AutoInboxHQ is an all-in-one email deliverability platform that helps you fix technical issues, keep a healthy sender reputation, and send campaigns at the exact moments your prospects are most likely to respond. It combines authentication checks, AI content analysis, blacklist protection, warmup, list cleaning, and a unique Signal Intelligence engine into a single, streamlined workflow.

Core deliverability tools

Email Authentication Verify SPF, DKIM, and DMARC for any domain in one click. Get a clear pass/fail view, an overall score out of 100, and simple “Fix It” steps so misconfigurations don’t quietly push you into spam.

Content Intelligence AI reviews your subject lines and body copy for spam triggers, readability, and deliverability risk. It flags risky phrases and formatting, then suggests cleaner alternatives so emails stay persuasive without tripping filters.

Blacklist Checker & Monitor Check in seconds if your domains or IPs are on major blacklists before you launch a campaign. Pro users can enable always-on monitoring that watches for new listings and alerts you immediately when something changes.

Warm-up Network Build sender reputation safely by connecting Gmail or Outlook to an automated warmup network. Free users join a shared pool; Pro users get dedicated pools for steadier results and more control over sending patterns.

List Validator Scan your lists to find invalid, risky, or low-quality email addresses before sending. Remove bad contacts to cut bounces, protect your sender reputation, and keep your deliverability metrics trending in the right direction.

Promo Tab Analyzer (Pro) Preview whether your email is likely to land in Gmail’s Promotions or Primary tab. The analyzer inspects structure, links, and content cues, then guides you on what to tweak so important messages show up front and center.

Signal Intelligence (Pro) Signal Intelligence tracks 80+ external signals—funding, hiring, tech stack shifts, reviews, news, and more—to spot when accounts enter a “buying window.” It scores and ranks prospects, estimates timing, and generates tailored outreach ideas so you contact the right companies at the right moment.
