The Best Cold Email Tools & Software for Sales Outreach Automation

The Best Cold Email Outreach Tools for B2B Sales Automation and lead generation

There are multiple uses for a cold email platform, from link building, press and public relations outreach, to lead generation. The process and mechanics between the various cases are quite similar. Sales automation tools can help staff improve their B2B outbound sales performance.

One such use of cold email tools is to help facilitate outbound sales automation. This process is commonly referred to as sales development, or demand generation. A good portion of the effort here is spent qualifying leads & prospects as to most effectively leverage the time of the account executives (AE’s), or “closers”. Configuring outbound email automation is a part of B2B outreach for lead generation, and includes setting-up drip sequences.

Email Warm-up Tools

Email warm up tools are necessary to use prior to launching your first cold email campaign. They help with maintaining your sender reputation and ensuring that your email address is not flagged as spam. Some are based on IP address, and others are for domains.

Outplay Logo

Outplay is a multi-channel sales engagement platform. Their cold email automation software also includes social outreach (LinkedIn, Twitter), SMS, and phone calls as a part of their cadence mapping system. Sales automation via outbound email marketing – which is also launching a new messenger CRM system, is a good sales outreach tool with a really nice reporting interface. It’s just as good as Sendbloom, in my opinion. They’re based in Canada and Ukraine.

The pricing model is based upon how many contacts you want to send to per month, and whether you want to add team members to your account. Cold Email Sales Automation Tool & Multichannel sales engagement platform

mailshake logo cold email tool sujan patel

Mailshake is the latest creation from Sujan Patel, originating from‘s outreach tool. It was first designed for a different type of outreach campaign – link building, where you send out emails to other sites asking if they can please post a link to your website on their page to help with domain authority and SEO. Another use for outreach emails is getting press coverage. So this process can useful for B2C businesses as well, just not for sales. They’re split from Austin, Texas to Australia.

Mailshake used to be one of the cheaper tools on the market, which is to say that you’ll only get what you pay for, as opposed to a high-quality cold email tool like Sendbloom,, or SalesLoft, perhaps. They had to turn off link tracking without a custom subdomain because it was causing messages to get flagged as spam, which is something you don’t want to happen in cold email automation marketing.

Mailshake used to cost only $10/month per account, but their prices have since gone up to $29 & $49/month. I had purchased a lifetime deal off of AppSumo, which apparently does not include access to their “Pro” tier of functionality. logo sales engagement platform manny medina and Max Altschuler

Sendbloom had a beautiful, easy to use interface! It had a direct integration with Salesforce, and was designed for enterprise sales teams. Sendbloom made segmentation easier when drafting new email campaign cadences with different templates and mail merge fields in the cold email copy. It was one of my favorite email outreach tools, but thankfully there are now plenty of sendbloom alternatives in the marketplace.

Sales Beach

Sales Beach Logo Tim Schwab

Sales Beach was one of the first cold email tools that I ever used as a beta tester years ago. While they are no longer trading these days, they were perhaps one of the earliest pioneers in the sales technology software. Their founder, Tim Schwab, is currently an entrepreneurial Sales Leader that advises companies.

Make no mistake, these cold email platforms & outreach tools are essential for B2B Lead Generation & sales enablement. You’ll need to have each one of your sales development representatives to have a seat. Don’t try to pinch pennies! If you have a product that the market values and have a scalable demand generation process, then the cost per seat of the lead generation software shouldn’t be an issue.

A key point to bear in mind when writing cold email templates for outbound sales is that you need to be as direct or succinct as possible. Don’t try to cram too much text into the email itself! If the recipient is smart enough, they will research your firm and perhaps browse your content, perhaps opting-in to your inbound content marketing funnel. Subsequent touches should be intelligent enough to reference any such action. If their timing is off, then don’t worry about them until they become a marketing qualified lead, for example.

This then means that you’ll have to choose cold email marketing software that has an API integration with either your CRM or marketing automation platform, or at least Zapier. You can find a good list of B2B Sales CRM’s here.
