InboxAlly
InboxAlly is an email deliverability platform founded in 2019 and headquartered in New York City. It uses a seed email network to generate real engagement on your outbound messages: opens, scrolls, link clicks, replies, spam rescues, and moves from Promotions to Primary. Those signals train inbox providers like Gmail, Yahoo, and Outlook to treat your domain as a wanted sender.
You add InboxAlly seed addresses to your sends through your existing ESP, CRM, or SMTP setup. The platform supports a REST API, native integrations with HubSpot and Klaviyo, and universal compatibility with any sender that can email a list. It does not require access to your email accounts, sending software, or DNS.
Dashboard tools include IA Score (ML-predicted inbox placement), IA Reputation (LOW/MED/HIGH domain rating), inbox placement testing, blacklist monitoring, DMARC reporting, and the IA Assistant for in-app deliverability guidance. Autowarmup can run hands-free with AI-generated warmup sequences. Standalone free tools cover spam checking, list verification, warmup planning, and SPF/DMARC record generation.
Paid plans start at $149/month for 100 daily seed engagements. A 10-day free trial is available with no credit card required.

How does InboxAlly improve email deliverability?
InboxAlly provides seed email addresses you add to your sends. When those seeds engage with your messages through opens, clicks, replies, and inbox moves, inbox providers learn that users value your content. That engagement strengthens sender reputation and improves inbox placement over time.
What are seed emails and how do they work?
Seed emails are unique addresses InboxAlly assigns to your account. You load them into your email platform alongside your regular recipients. When seeds interact with your messages, those actions signal to providers like Gmail and Yahoo that your emails belong in the inbox.
Does InboxAlly require access to my email account or DNS?
No. InboxAlly never requires access to your email accounts, sending platform, or domain DNS. You add seed addresses to your sends and the platform handles engagement from its network.
How long until I see deliverability improvements?
Most domains see measurable inbox placement improvements within 2 to 4 weeks of consistent use. Damaged or new domains may need 4 to 8 weeks for full reputation recovery. IA Score and IA Reputation dashboards update continuously so you can track progress in real time.
Is there a free trial?
Yes. InboxAlly offers a 10-day free trial with no credit card required. You can explore Autowarmup, the dashboard, the IA Assistant, and the free deliverability toolkit during the trial period.
