"Effective Cold Outreach with Growth Potential"
3.5/5
What do you like best about Instantly?

I like that Instantly makes it easy to create email campaigns and insert leads with API support. I also appreciate how sending emails directly to inboxes with their done-for-you service helps host my emails efficiently. The ability to track each lead's response is useful, and managing warmup emails is simple with just a click, ensuring my domain health is maintained through a pure network.

What do you dislike about Instantly?

I still don't understand the website visitors feature even after almost a year of use, and the pricing is kinda high. Review collected by and hosted on G2.com.

"Best for my Sales Campaign"
5/5
What do you like best about Instantly?

I have been using the platform and yes, its definietely worth a try, there is a lot to do on the dashboard, many options to choose from. I particularly like the supersearch function, where you can choose filters like "Job titles", "location", to get the exact details of all the prospects. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

I don't feel there's any downside to this platform; the dashboard looks minimal, and the tool is extremely helpful overall. Review collected by and hosted on G2.com.

"Great Bulk Sending and Open Rates, But Tough Domain Setup and Spam Concerns"
3.5/5
What do you like best about Instantly?

It allows for bulk sending from multiple email domains so we don’t get flagged as spam. It also has insane open rates Review collected by and hosted on G2.com.

What do you dislike about Instantly?

The setup was horrific if you buy your domains outside the platform—it was so hard to connect everything. Also, anyone whose email gets uploaded ends up being sent a lot of spam. Review collected by and hosted on G2.com.

"Effortless Email Management with Instantly"
5/5
What do you like best about Instantly?

I really like how Instantly makes getting everything set up super easy and affordable. It's amazing that you can be ready to go with email accounts in just fifteen minutes. I love that it allows me to manage as many email accounts as I want and the accounts are pre-warmed for me, which is super nice. This means I don't have to worry about getting marked as spam. It's really convenient that I can spin up email accounts ready to go exponentially faster than I could manually. Overall, I think it's a huge value for anyone doing email outreach. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

Nothing really. It's exactly what I need. Review collected by and hosted on G2.com.

"User-Friendly with Stellar Support, Needs Better Automation"
4/5
What do you like best about Instantly?

I really like the ease of use with Instantly, as the navigation and user interface make it very simple and logical to see the performance and metrics of my campaigns, or to make updates. The Unibox feature is a time-saver, allowing me to quickly view responses by status or campaign and identify what's working and what isn't. The biggest standout for me is the support chat; I use it a lot, and they are super quick and helpful, which is especially important since I'm not technical or an expert in cold email campaigns. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

Automated campaign optimization - it learns automatically to update ICP (Leads) and Campaign and messaging, currently this is manual and it would be great if this can be an automated campaign that learns on auto-pilot to optimize leads (ICPs), the sequences, variants, and responses based on the KPIs and goals of the campaign. The initial setup took some time, especially the domains and first campaign setup and lead generation, as I didn't fully understand how best to do this and the lead quality and relevance were not on target, for example, I tried to get Dental Practice owners and got random results like Vet clinics and beer breweries.

"Instantly Made Email Warm-Up Easy and Kept My Campaigns Out of Spam"
4.5/5
What do you like best about Instantly?

I recently started a new product with a different domain and different email address. I used Instantly to warm up the email and make sure that none of my emails landed in spam. At first I couldn't even send emails to people I knew and now I can do campaigns without any issues in just a couple of weeks. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

Not much at the moment. I think it has been intuitive and helpful to achieve what I need. I have't used much of their email automation features, so we will see. Review collected by and hosted on G2.com.

"Effortless Cold Outreach with Instantly"
5/5
What do you like best about Instantly?

I like Instantly because it offers high deliverability, quick setup, and easy management of campaigns. I find it really easy to use, which is a big plus for me. The purchasing of inboxes and domains is simple and straightforward, and I can add inboxes whenever I need at a low cost. This feature helps my campaigns run smoothly and on time, especially when I'm reaching out to larger volumes. I also use Instantly integrated with Hubspot, and it seems to be the best tool on the market for cold outreach. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

There is nothing I dislike. The product is great, and the service is even better Review collected by and hosted on G2.com.
