"Game-Changer for Cold Email Deliverability with MailWarmupPro"

5/5

What do you like best about Mail Warmup Pro?

I’ve been using MailWarmupPro for a few weeks now, and it’s honestly been a game-changer for my cold email outreach. The setup was really quick—I connected my Gmail and Outlook accounts in just a few minutes. After about 10 days, I noticed my emails were landing in inboxes instead of getting sent to spam. Review collected by and hosted on G2.com.

What do you dislike about Mail Warmup Pro?

Honestly, the only thing I dislike is the pricing. For a solo founder like me, it feels a bit expensive compared to some other tools. Also, I wish there were more direct integrations with other CRMs. But apart from that, it does what it promises, so I can't complain much. Review collected by and hosted on G2.com.

What problems is Mail Warmup Pro solving and how is that benefiting you?

Before using MailWarmupPro, my cold emails were landing in spam and I was wasting hours manually warming up inboxes. Now it's automated and my emails actually reach the inbox. I've seen a big jump in reply rates and I don't have to worry about my domain getting burned. It saves me time every week and lets me focus on outreach instead of deliverability headaches.

"Strong Deliverability Results, but Setup Could Be Simpler"

5/5

What do you like best about Mail Warmup Pro?

I like the pricing and ease of use. I like the reply and thread management, with complex exchanges across two or three email threads instead of just two emails, which makes it more reliable and gives a truer reputation. It helps with email deliverability and improving email reputation. Review collected by and hosted on G2.com.

What do you dislike about Mail Warmup Pro?

I’d make the UI simpler, with the same page for adding mailboxes and starting warmup. The initial setup was a bit tough. Review collected by and hosted on G2.com.
