Instantly has a overall clean UI compared to it's competitors which is quite easy to understand and get across fast even for folks starting their cold email journey, The other added benefit of using it is it's google workspace and hubspot integration which fits well with my overall workflow of sourcing leads from apollo then using clay in enrichment while syncing with hubspot. It acts as a management layer. Performance wise instantly is considerably good and if used properly it helps manage warmups, sending limits and campaign performance well. The other benefit is it's ability to connect multiple inboxes which is more cost effective than other tools i've used which usually cost per seat. Instantly's docs are good enough for onboarding and the support is quite responsive. The AI intelligence features given through its copilot are good in automation and getting an overall picture of the campaigns. Review collected by and hosted on G2.com. What do you dislike about Instantly? Instantly has an issue with deliverability uncertainty, even with warmups, inbox rotation & sending limit there are still a lot of trial and error loops I have to jump through, so some times campaigns look good inside instantly but the replies suddenly drop due to emails landing in spam. I also have an issue with advanced support, where even tho the product itself is fine and easy to understand but for more nuanced queries with DNS setup etc. I had to jump a lot of hoops to get everything set right, The AI setup they've been pushing is also based on lighter AI models which lack the nuance of advanced thinking with the more sophisticated models which reflects on the kind of responses it some times generate for things like cold emails etc. Review collected by and hosted on G2.com. What problems is Instantly solving and how is that benefiting you? Instantly solves the problem of collating all the different sources our team uses for outreaches where instead of having to deal with separate inboxes , sheets and manual follow ups, It brings everything into a single platform which makes the overall monitoring and operations aspect of it easy. Also reply management which happens via unibox helps in faster reviews and helps save on loosing potential opportunities due to distributed setup for our team.
