What tools to use to scale outbound campaigns

As we have explained in previous installments, marketing strategies based on cold emails have established themselves as the kings in terms of performance. However simple as it may seem to send emails to profiles of interest, this practice requires solid foundations to achieve a successful campaign.

Sending a cold email is the perfect channel for lead acquisition and if combined with the right choice of technology tools can achieve great results.

What is a tech stack? How can I choose the right one for me?

A technology stack is a set of specialized software capable of increasing your efficiency, productivity, and profitability thanks to its tools. Although there are currently more than 9,900 tools on the market capable of supporting sales and marketing teams, not all of them can adapt to your needs and many may even hinder your productivity.

Strategy first, technology second

To choose your tech stack correctly you should look at them as pieces of a puzzle, based from the start on what areas you want to complete. Your main guide should always be your objectives and the integration with the tools you have at hand.

In the case of sending cold emails, a chain of tools (or a couple of them that cover all the necessary steps) is required due to the complexity of the process, such tools will bring out the best of you or your sales team; the tech stack you build has to manage to help you in the acquisition of Data, email warm-up and correct management of your emails plus the monitoring for the generation of reports.

Skief Labs team, you should base your choice on two main categories: data acquisition and cold emailing automation.

Which technology should I choose for data collection?

In most marketing strategies and teams, data acquisition and management are one of the most underestimated needs, even though it is practically the basis of lead acquisition.

For your data to function optimally, it needs to go through 4 important processes: aggregation, enrichment, cleansing, and verification. Although this can be achieved through the use of various tools, keep in mind that lack of integration can cause you worse problems.

Which data provider should I choose?

What tools can I use to send my e-mails?

It is important to differentiate between the types of sales emails that your company can generate: cold emails (B2B) and promotional emails or newsletters, part of B2C communication.

What tool do I need to send my cold email campaigns?

Before you start sending cold emails you must take certain aspects into account to avoid your messages going directly to your spam folder.

Consider that you must protect yours as much as possible your company's domain, for this reason, the most advisable thing is always to have an alternative domain that continues to be identifiable. For example, (original domain) for

Once you have generated an email that protects your domain, you cannot venture to send hundreds of emails to strangers, because service providers would quickly notice, passing your address to the dreaded spam list.

One aspect you should also consider is which email provider can help you the most. Although there are hundreds of options, the market is dominated by two giants: Google Workspace and Microsoft.

Consider to whom you are going to direct your messages before choosing one, Microsoft can be your platform if you intend to reach large companies or Google if your target audience is concentrated in small and medium companies.
