Even though there are now more social networks, content sharing platforms, and forums than before, email remains one of the best channels for promoting products and businesses. Aside from marketing campaigns, the technology can also help in generating leads, requesting backlinks, and connecting with the right influencers for publicity, commonly known as email outreach.
However, since such work requires sending to multiple recipients, repetitive tasks, and data analysis, using the usual email clients/apps might make the job more tedious and the results less effective. Thankfully, leading email providers are now more capable than ever, and companies can choose from countless dedicated email outreach tools, like the seven best options in this article; please read on.
7 Best Email Outreach Tools for Cold Emails and More
1. Gmail

Features:
- Multiple recipients sending
- Message scheduler
- 3rd party plugins support
Gmail is the most popular email provider worldwide, and for good reasons: it’s free, easy to use, and can work for casual users, professionals, or even marketers. In terms of usability for performing email outreach, Gmail should suffice for the fundamental tasks. As such, even in the base plan, it’s possible to send unlimited emails (though with a certain limit per day) to multiple recipients and can range up to 2,000 people per mail for Google Workspace subscribers. Moreover, other features like message automation allow companies to maintain regular sending schedules or follow specific email delivery timings without the risk of forgetting.
As an indirect answer to the lack of built-in analysis features, Gmail supports thousands of 3rd-party plugins from the Chrome Web Store. Accordingly, this unlocks many possibilities in using the service, including the ability to track the number of opens and clicks of sent emails through extensions like Gmass. However, if the basic functions of Gmail are enough for an organization, then using a native client for it, like Boxysuite , would be beneficial. Unlike browsers, Boxysuite provides a clutter-free, productive, and focused environment for Gmail and other Google Apps like Contacts, Calendar, and Keep on macOS.
Pros:
- Offers an excellent free plan
- Minimal and easy to use
- Integrates with Google Contacts for faster email sending
- Supports 3rd party plugins for more functions
Cons:
- No built-in data analysis features
2. NinjaOutreach

Features:
- Massive influencer database
- All-in-one CRM
- Sent email tracking
- Collaboration and team member controls
Apart from generating sales leads, many companies also use email outreach to connect with relevant influencers. Currently, these personalities help businesses promote new products or establish the brand quickly and effectively. Regardless, for such tasks, NinjaOutreach proves to be the best choice for most marketers. In detail, it has a massive database of influencers from Instagram and YouTube and allows users to find the most suitable ones using niche keywords quickly. After that, it will display all necessary information about the discovered influencers, including names, content backgrounds, and especially email addresses.
While the database feature alone is enough reason to get the service, NinjaOutreach’s all-in-one CRM can help many companies that value organization and ease of operations. As such, its CRM can replace many tools like Excel or Google Sheets for collecting client details, conversations, and more valuable data. Also, it offers flexible search, view, and filter functions, so users can easily locate something even from thousands of entries. Lastly, as a vital feature for email outreach, the service allows tracking sent email clicks, opens, and replies.
