WarmInbox

We had just launched a new domain and needed to warm it up properly. This app took care of everything automatically. Our cold email deliverability is now exactly where it should be.

I didn’t know much about inbox warmup, but this app made it simple. It helped improve email sender reputation, and our marketing emails are performing much better now. Totally worth it.

After connecting this app, we saw email open rates go up and spam complaints drop. It just runs in the background, which is exactly what we needed. A solid tool for rebuilding email reputation

We send a lot of follow-up and review request emails, and deliverability was becoming a problem. This app helped us boost open rates and stop emails from landing in spam. Highly recommend it for email warmup.

I kept wondering why customers weren’t seeing our emails. Turns out they were going to spam. This app helped fix that fast. It’s perfect for Shopify deliverability, warmup, and sender score recovery.

I connected the app, and within days I noticed better inbox placement and a drop in bounce rates. Works well for me.

Our open rates jumped from around 10% to just over 50% in just one week after using this app. It completely fixed our spam issues and helped restore our sender reputation. Couldn’t believe how fast it worked. Definitely a must-have for any Shopify store relying on email.

We’ve tried a few email warmup solutions before, but WarmInbox is built specifically for Shopify, which made the whole process so much easier. Our sender score improved quickly, and we finally stopped worrying about emails getting flagged. It’s the perfect solution for domain reputation recovery, right where we need it.

We installed this app to fix our email spam issues, and it actually worked. Open rates jumped, and customers are finally seeing our emails. Wish there were a bit more control over the warm-up speed, but overall it’s doing the job.

I use email a lot for Shopify promos and abandoned cart reminders. This tool helped me warm up my inbox, and now my messages land in inboxes instead of junk. It’s been a game-changer.

So far, so good. My inbox is getting traffic, and I haven’t had any issues. The only thing I’d like to see is a way to integrate this with my outreach tool to get a better overall picture of my email performance.

One thing I like is that WarmInbox doesn’t interfere with my email campaigns—it just warms up my inbox in the background. I’ve tried tools that mix warm-up with outreach, and it always gets messy. This keeps things separate, which I appreciate.

I like that I don’t have to adjust anything—the app just follows a natural warm-up schedule on its own. Other tools I’ve used required too much manual tweaking, which made the process more complicated than it needed to be.

I love that I can see my email health score, so I know when my inbox is ready for sending. It’s been running for a few days now, and everything seems smooth. Hoping to see a real difference in my deliverability soon.

I appreciate how hands-off this process is. I don't need to monitor it everyday; it just run in the background.

Support was quick to respond when I had a question, which I really appreciated. The app itself works well.

Good app overall, but I’d like more insight into how my inbox reputation is actually improving. The health score is helpful, but more details on what’s influencing it would make it even better.

I've tried other warm-up tools, and this one is by far the easiest to use. Emails come in at a steady peace, and everything looks natural. Excited to see how it impacts my deliverability over the next few weeks!

It’s easy to set up, and I like that it runs in the background without needing my attention. However, I had a minor issue where the warm-up paused unexpectedly, and I had to contact support. They were quick to respond, but I wish there were an alert system to notify me.
