LiftInbox is an automated email warmup service built to solve one of the most common and costly problems in email marketing: well-crafted emails that never reach the inbox because of poor sender reputation or missing authentication records.

The Problem: Why Are My Emails Going to Spam?

Every day, businesses spend hours crafting the perfect email — compelling subject lines, valuable content, clear calls to action — only to see it vanish into the spam folder. The frustrating part is that this usually has nothing to do with the email's content. It comes down to sender reputation, a trust score that inbox providers like Gmail, Outlook, and Yahoo assign to every sending domain and IP address.

New domains, inactive email accounts, sudden sending volume spikes, and missing SPF, DKIM, or DMARC records are the most common causes of poor deliverability. Without addressing these root causes, even the best email content will continue landing in spam.

What Is Email Warmup

Email warmup is the process of gradually building sender reputation by sending a small, controlled number of emails per day and slowly increasing that volume over time. Each email gets opened, replied to, and engaged with, training inbox providers to recognize the sender as legitimate and trustworthy.

How LiftInbox Works

LiftInbox automates the entire email warmup process. Once connected via SMTP and IMAP credentials, the platform performs a complete domain warm up over a 30-day cycle:

- Week 1: A small number of emails are sent daily, establishing initial sending history.

- Week 2-3: Sending volume gradually increases, building engagement signals.

- Week 4: Volume reaches a healthy sending level, and sender reputation is fully established.

Every warmup email is sent to a network of real, high-reputation inboxes that automatically open, read, and reply to each message. If any warmup email lands in a spam folder, LiftInbox automatically rescues it — moving it to the inbox, marking it as not spam, and flagging it as important. This directly trains Gmail, Outlook, and other providers to trust the sending domain.

Complete Email Deliverability Service

Beyond warmup, LiftInbox functions as a full email deliverability service and email deliverability checker. The platform monitors SPF, DKIM, and DMARC authentication records every single day, sending instant alerts the moment any record breaks — whether due to a hosting change, provider switch, or DNS misconfiguration.

A real-time dashboard displays the sender reputation score alongside the inbox versus spam placement rate, giving complete visibility into email deliverability health at any moment.

Who Uses LiftInbox

LiftInbox is built for small businesses, marketing agencies, SaaS founders, and cold email marketers who need to:

- Warm up a brand new domain or email address before sending campaigns

- Repair a damaged sender reputation after spam complaints or blacklisting

- Maintain consistent inbox placement for ongoing email marketing or cold outreach

- Monitor authentication records without manually checking DNS settings

Compatibility

LiftInbox connects through standard SMTP and IMAP protocols, making it compatible with virtually any email provider, including Google Workspace, Microsoft 365, Amazon SES, Mailgun, SendGrid, Zoho Mail, and cPanel-based hosting.

Why It Matters

Improving email deliverability isn't a one-time fix — it's an ongoing process built on authentication, warmup, list hygiene, and consistent sending habits. LiftInbox automates the most technical and time-consuming parts of this process, so businesses can focus on their campaigns instead of fighting spam filters.
