Instantly dominates the discussion on cold email tools and outreach in general. If you run an agency, you’ve probably come across it at some point in time and wondered whether or not it lived up to the hype and could help you deliver for your clients. 

Fortunately, you don’t have to wonder much longer. This article will give you an honest look at the platform to help you make the best possible decision for your agency. 

Instantly Overview

It offers tools for every step of the cold email process and uses AI to help you engage more effectively and achieve a better return on investment for clients. 

Instantly Core Cold Email Functions

The first thing any agency in the lead generation or marketing business looks for is great prospecting tools; you need to be able to find high-quality leads before you can do anything else, after all. Instantly’s got that covered with an absolutely massive built-in B2B database of over 450 million leads, all of which are pre-validated with the platform’s proprietary multi-layer verification process. This database has wide coverage across industries and geographic areas, so that anyone can find their ideal leads there.

Once you’ve found some leads, Instantly lets you connect unlimited email accounts to scale as quickly as you need, and it offers AI-powered optimization so that only the best outreach reaches your prospects. This includes AI-powered features such as a content writer with Spintax, a spam checker, an inbox manager, and more.

Deliverability Suite

  • Slow Ramp email warming, which launches with a single click and simulates the frequency and cadence of organic human email traffic to prepare accounts for outreach ahead of your actual campaign. 

  • Inbox placement testing that analyzes where your mail lands to deliver actionable insight on how to improve your positioning and sender reputation

Customer Relationship Management

Instantly features a built-in CRM to help agencies manage leads and convert more of them into repeat customers for clients. It features a master inbox with unlimited seats for all team members, along with all Instantly’s great AI features. This CRM even gives users access to call and SMS functions right from the Instantly interface to help lock down and better serve leads. 

Email Accounts & Infrastructure 

In addition to unlimited email accounts and all its other great features, Instantly also offers users some email infrastructure to get started at scale faster. This includes done-for-you Google email accounts and sending domains ready for immediate outreach. 

Instantly uses high-quality US IP Google Accounts to ensure you start on the best footing and sets up MX Records, SPF, DKIM, and DMARC to the best available industry standards.

Instantly’s AI Copilot - An AI-Powered Game Changer

Instantly’s entire toolkit is top-tier, but what really ties it all together is the platform’s proprietary AI Copilot, a feature that works like ChatGPT for outreach and sales. By interacting with and prompting the AI model in plain, everyday English, users can have it carry out tasks as complex as generating an entire campaign or auditing a workspace. This powerful AI capability enables even quicker, more efficient use of Instantly. 

In addition to its core functionality, Copilot also offers two distinct and powerful features: Tasks and Memory. 

  • With Copilot Tasks, users can set up Copilot to automate recurring campaign tasks that require constant human attention. It can be set to repeat these tasks daily, weekly, or monthly, and can even integrate with Slack and other platforms to send messages. 

  • Copilot Memory is even more potent for prospecting and outreach: Instantly’s AI analyzes your business or campaign to understand it better, and then uses that information and profile to improve your prospecting with more accurate segmentation and boost response rates with even more personalized email copy. 

Even with a laundry list of top-class features, AI Copilot still stands out as Instantly’s most impressive offering.
