What’s the difference between informational vs promotional newsletters?

You've probably subscribed to two very different kinds of newsletters without realising they're categorised differently in the eyes of email law. One tells you something useful. The other tries to sell you something. The distinction matters more than most senders think.

Informational newsletters are primarily there to inform. Think a local council sending road closure updates, a nonprofit sharing its quarterly impact report, a university emailing students about campus hours, or a trade association updating members on regulatory changes. The reader signed up to stay in the loop, not to browse a catalogue.

Promotional newsletters exist to drive a commercial action. A fashion retailer's weekly sale alert, a SaaS company's "upgrade to Pro" campaign, a restaurant's "book this weekend" email. Even if these emails include useful content, their primary purpose is to move a reader toward a purchase or conversion.

Why does the difference matter? Because consent rules, and in some jurisdictions legal obligations, treat them differently. Under consent frameworks, purely informational emails often have more flexibility, especially in B2B contexts or for existing relationships. Promotional emails almost always require explicit, affirmative consent and a clear unsubscribe path.

The tricky part is that most real newsletters sit somewhere in the middle. A weekly digest that shares three industry articles and then plugs a product at the bottom is promotional in the eyes of most regulators, even if the content is genuinely useful. The rule of thumb used in many legal assessments is to ask what the primary purpose of the email is. If it's to sell or convert, it's promotional. Full stop.

There's also a deliverability angle here. Gmail and other mailbox providers sort emails by inferred intent. Informational emails that arrive on schedule and get opened reliably tend to land in the Primary tab. Promotional emails, even well-designed ones, often get routed to the Promotions tab. If your newsletter blends both types and you're seeing Promotions tab placement, splitting your content strategy into two separate sends (one informational, one promotional) can actually help each one land where it belongs.

Now if you're not sure which category your newsletter falls into, ask yourself this: if there were no link to buy anything, no CTA, no discount, would readers still find it valuable enough to open? If yes, it's probably informational at its core. If the content only makes sense as a wrapper around the offer, it's promotional.
