Email is the least glamorous channel in digital marketing and consistently the most profitable, returning more per pound than any social platform. It is also genuinely skilled work, which is why "can you build an automated email campaign?" is such a common interview filter.
What email marketing training must cover
A serious email curriculum has five parts: campaign design (structure, copy, subject lines that get opened), segmentation (sending the right message to the right slice of the list), automation (welcome sequences, abandoned-basket flows, re-engagement journeys), lead generation (building the list ethically in the first place), and deliverability plus measurement (staying out of spam, reading open, click and conversion data).
Platform courses vs marketing courses
Free academies from Mailchimp, Klaviyo and HubSpot teach their own tools well and are worth doing. But email only makes business sense connected to everything around it: the landing pages that capture subscribers, the content that feeds campaigns, the analytics that prove revenue. Email-only training leaves you knowing the instrument but not the orchestra.
Learning it inside the full stack
In Digital Marketing in Practice, a dedicated email marketing and CRM module - campaign design, segmentation, automation, lead generation - ends with you building a real automated email campaign, and the modules around it supply the content, landing-page and analytics skills email depends on. During the guaranteed 12-week placement, email marketing is one of the tasks learners most commonly run for their host organisation, which is exactly the experience employers ask for.
The bottom line
Choose email training that is hands-on, automation-focused and embedded in the wider marketing stack. An inbox campaign you have genuinely built and measured will say more in an interview than any certificate.
