I use SalesRobot for cold email and LinkedIn outreach, and I like that it is stable. After years of using it, I've never been penalized by LinkedIn, which makes it a very safe tool. Review collected by and hosted on G2.com.

Email warmup would be nice. It allows you to add emails outside of your LinkedIn email address but... it doesn't have an email warmup feature; it has to be warmed up already. But to be fair, I feel they built this for your LinkedIn audience, not a true cold email tool, so it makes sense that they don't but... I would love it. Review collected by and hosted on G2.com.
