Modern cold outreach is a trial by fire, and every marketing team, lead generation agency, and freelancer needs to reach more people much faster and on a larger scale. It’s no wonder so many people want the best software tool for the job, and in many spheres, the clear answer is Instantly. It’s everywhere, and if you’ve never used Instantly yourself, it might all seem a bit overstated. It can be that good, right?

Well, that’s where you’re mistaken. To earn the title of best cold outreach tool, a contender should be able to clear the competition in four essential areas:

● Lead generation

● Deliverability

● Outreach

● AI integration

This article will cover what Instantly has to offer in all four of these areas, and in the process, show you why it’s the best cold outreach tool for any outreach campaigns you might be looking to organize.

Why Instantly Is the Best Lead Gen Tool

The first step in cold outreach is finding leads to reach out to, and it’s one of the most difficult parts of the entire process. Instantly features a massive B2B database with more than 450 million pre-validated leads to select from across industries and locations all over the world.

To make finding your specific leads easier, the Supersearch tool includes several powerful prospecting features that quickly identify your ideal leads.

Key features: 

● AI-powered search that takes your natural language description and turns it into a shortlist of relevant leads.

● Advanced filters that let you use signal and other insights to filter leads, alongside regular search parameters.

● Lookalike feature lets you clone existing clients by creating an ideal custom profile based on your clientele, then automatically finding leads that match that profile.

● Lead enrichment across several methods, including waterfall enrichment from 9 trusted sources and AI-powered site scraping on lead websites.

● Website visitor identification to automatically add warm B2B leads already looking into your business, service or event directly to your outreach campaign.  

Why Instantly Is the Best Deliverability Tool

Emails need to actually land in inboxes to get your return on investment, and so deliverability is key. Instantly’s approach to deliverability is clear and straightforward: verify every lead, warm every email address before and during outreach, and test inbox placement if things seem off. Like with its prospecting approach, the platform has a bunch of useful tools to make this effortless.  

Key features:

● Multi-layer email verification for all leads in the database, and automatically applied for external leads that covers syntax and format checks, domain and MX records, SMTP mailbox testing, multiple risk screens, and much more

● Slow ramp to emulate human email sending patterns to automate email warming while fooling ISP systems looking to penalize automation.

● Deliverability dashboard for gauging your deliverability in real time and making adjustments wherever necessary.

● Unlimited, automated email placement testing for continuous assurance and proactive insights.  

Why Instantly Is the Best Outreach Tool

Outreach is the core functionality for Instantly, and it delivers here too. With the previously mentioned lead enrichment for deep personalization and AI integration to take the creative strain off and let users focus on other issues, it’s yet another clear winner compared to the competition.

● Unibox interface to manage conversations across all accounts in one place.

Why Instantly Is the Best AI-Powered Platform

Instantly has AI integrated into every part of its offerings, including five major LLMs built right into the Instantly browser interface. The pinnacle of this AI-powered strategy is Instantly’s AI Copilot. This proprietary AI assistant works like ChatGPT for outreach and sales.

The platform has also shortlisted new features to automate the entire process fully by default.

Instantly Is the Best All-In-One Platform

In summary, users will be delighted to find that Instantly offers:

● A massive B2B database with pre-validated leads.

● Extensive, exhaustive deliverability tools to protect your sender reputation and ensure you don’t end up in spam folders.
