With email deliverability, there is no metric as important as trust. And trust starts with Email Consent. If someone hasn’t agreed to hear from you, your emails are more likely to end up ignored, flagged as spam, or even worse, get your brand into legal trouble.

Consent in email marketing is very important, and in the article, I discuss how you can collect and use it the right way.

What Is Email Consent?

Email consent is simply the permission a person gives you to send them marketing emails. It’s the foundation of respectful and effective email marketing communication, and without it, you are risking deliverability issues and your reputation.

There are two main types of email consent, express and implied consent. 

  • Express consent: The subscriber actively agrees to receive your emails, often by checking a box or confirming through a double opt-in.
  • Implied consent: The person has an existing relationship with your business (like being a customer), but hasn’t formally signed up for emails.

While implied consent exists, the gold standard is always express consent because it’s clearer, safer, and more sustainable especially if you hope to maintain a long-term relationship. 

Why Consent Matters in Email Marketing

  1. Better Deliverability – When people actually want your emails, they’re more likely to open, click, and engage. This boosts your reputation and keeps your emails out of the spam box. 
  2. Legal ComplianceEmail compliance laws like GDPR in Europe, CAN-SPAM in the US, and CASL in Canada all require consent for marketing emails. Ignoring this can have legal implications.
  3. Stronger Relationships – Starting with consent shows respect. It tells subscribers you value their choice, and in turn, makes them more likely to trust your brand.
  4. Fewer Complaints – Subscribers who never agreed to your emails are often the first to hit “spam.” With proper consent email marketing, that risk is reduced drastically.

GDPR and Consent Emails

Under GDPR, GDPR consent emails must follow strict rules:

  • Consent must be freely given, specific, informed, and unambiguous.
  • Pre-checked boxes don’t count.
  • People must be able to withdraw consent just as easily as they gave it.

This means you can’t hide your opt-in inside small print or assume silence equals agreement. Transparency is key.

How to Ask for Consent the Right Way

Getting consent isn't complicated, what matters most is clarity. Here are some tips for your consent email template or sign-up forms:

  • Use clear email consent wording like:
    “Yes, I’d like to receive weekly updates and special offers from [Your Brand].”
  • Be upfront about what kind of content you’ll send (newsletters, promotions, updates).
  • Place a clear unsubscribe link in every email.
  • Use double opt-in so subscribers confirm their address and interest.

The Risk of Skipping Consent

Skipping consent might give you a bigger list in the short term, but it backfires quickly. And some of the clear indicators you'd start to notice are; higher bounce rates, more spam complaints and lower engagements which will invariably do damage to your sender reputation. And once your reputation is damaged, even people who do want your emails may stop seeing them in their inbox.

Final Thoughts

By being transparent, respectful, and compliant, you’ll send better campaigns, protect your brand, and prevent your mails from going to spam.
