Pros & Cons from Real Users

Pros

  • Over time, the platform helps improve email deliverability in a noticeable way, especially for users running cold email campaigns or outreach strategies consistently
  • Easy to use with a clean interface, saves time, and helps improve online visibility and engagement. It’s beginner-friendly and doesn’t require much technical knowledge to get started, which makes it very convenient.
  • It's reliable and runs automatically, so I don’t have to constantly check it. It also handles multiple accounts really well, even when you’re working at scale. The fact that it works across different email providers is a big plus for us. I also like having the spam score there to quickly see if everything is okay.
  • Mailwarm is an excellent email warm-up tool for improving email deliverability and sender reputation. The automated warm-up process gradually increases sending volume, helping emails land in the inbox instead of spam. It supports domain and IP warm-up, integrates easily with common email providers, and is ideal for cold email outreach, SaaS, and marketing campaigns. The dashboard is clear and the setup is fast, even for non-technical users.

Cons

  • The platform offers limited advanced customization options, which may not satisfy experienced users looking for more control over the warm-up process
  • Some advanced features are limited, and there is room for improvement in speed and overall performance during heavy use.
  • So far it’s been doing what we need, no complaints.
  • Advanced users may want more granular reporting on inbox placement and spam signals, but the core email warm-up functionality works very well. I told to the support they said that they will launch spam score feature in the coming weeks.

Pros & Cons from Real Users

Pros

  • None. There is nothing I liked working with this company. Their interface is poor, no support, no reporting. Nothing.

Cons

  • 1. Support is totally non-existent. I wrote their support the first time the 18th of June '25 and still have not receive ANY reply 2. When I bought Saleshandy (doing false advertising claiming 'unlimited warm' which you don't get) they told me that the existing TrulyInbox subscription would be cancelled and I would get linked with their system. That was a lie and the subscription did not get cancelled. And again support is not responding for a refund. 3. Connection to random inboxes is lost and neither their system or support helps to solve it 4. They don't show stats of emails send for warm-up. Only from yesterday but not over time. 5. their system does not adhere to the 'daily increase' of warm-up as per config at all
