Let’s get straight to it.
TL;DR: Apollo Email Warm-Up Alternatives Comparison (2025)
Why People Are Searching for Apollo Email Warmup Alternatives
Apollo email warmup is gone.
No warning. No setting. No support article. It just quietly disappeared.
I kept seeing the same question across Reddit, G2, and Slack groups:
“What happened to the Apollo email warmup feature?”
The answer? Apollo completely removed it and never replaced it with anything else.
What Changed?
- Apollo used to offer a basic email warmup feature.
- It helped new inboxes build trust before sending cold emails.
- Now, the Apollo email warmup no longer exists.
Why It Matters
- Users are sending cold emails without any warmup at all.
- There’s no pacing, no reputation building, no inbox simulation.
- Deliverability drops fast, and domains get flagged or blacklisted.
That’s exactly why I created this guide: to break down the top 5 Apollo email warmup alternatives real users are now relying on.
What Should You Look For in an Email Warmup Tool? (Questions to Ask Before Choosing)
If you're replacing Apollo’s missing warmup feature, here are the most important questions to ask before choosing a new one:
❓ Can I control the warmup speed and volume?
You should be able to decide how many warmup emails are sent per day and how quickly the volume increases, especially for new domains.
❓ Does it simulate real inbox activity?
The best tools don’t just send, they also simulate opens, replies, stars, and engagement, which helps build a real sender reputation.
❓ Will it show me inbox health and reputation?
Look for tools that give visibility into spam placement, sender score, and bounce rates, so you know your inbox is actually improving.
❓ Does it help me set up SPF, DKIM, and DMARC?
DNS records are critical. A good warmup tool should either check your domain setup automatically or guide you through fixing it.
❓ Will it send alerts if something breaks?
You don’t want to guess. If your domain is blacklisted or an inbox is underperforming, the tool should tell you immediately.
❓ Can it scale across multiple inboxes?
If you're managing outreach across different inboxes or domains, the tool should support multi-inbox warmup with centralized control.
