2. Instantly.ai

G2: 4.8/5 ⭐(3,400+ reviews)
Capterra: N/A

In my opinion, Instantly is the best AI-powered cold email service provider, as they have a lot of AI-led features in their platform, such as: 

• AI Sequence Writer
• AI Inbox Manager
• AI-Personalized messaging
• AI reply suggestions

Moreover, Instantly’s free trial gave me a preview of its lead finder, which lets you prospect with the help of AI. You can give a prompt, and it will get back to you with the results. 

 Even its campaign builder was easy to use and allowed me to create sequences seamlessly.

However, what disappointed me the most was that Instantly’s free trial limited my access to many features like AI Sequence Writer and AI Spintax Writer, which prevented me from checking the quality of the AI-generated email copies.

That said, after the 14-day free trial, the account will be blocked, and you won’t be able to use Instantly without subscribing to a plan.

Unlike other tools, it offers advanced warm-up features like AI-powered warmups,  high-deliverability IP servers, spam rescue, ESP matching, and deliverability tests. 

That said, the rest of the features are a bit more standard. You can automate and personalize cold emails, verify email addresses, and see your campaign stats using a decent analytics suite.

That said, in my experience, it is a solid tool if you are looking to do more than just sending emails, as you get access to a unified inbox, LinkedIn automation, power dialer, and lead temperature tracking.

Also Mailshake’s AI email writing tool, SHAKEspeare, made it easier for me to write personalized emails  — All I had to do was enter a prompt specifying the desired tone, length, and other parameters.
