Question : What are the advantages and disadvantages of email marketing?

The main advantages of email marketing are its low cost, its high return on investment, the fact that you own your contact list and that every result can be measured. Its disadvantages are the risk of landing in spam, crowded inboxes and the need for every recipient's consent.

Advantages of email marketing

• Low cost. A send costs a fraction of a paid ad and does not depend on bids or algorithms.
• An audience you own. Your list belongs to you: if a social network changes its rules, your subscribers are still there.
• Measurable return. Opens, clicks, conversions and unsubscribes are tracked for every campaign. See what a good email ROI is.
• Personalization. With contact segmentation, each group receives a different message based on its data or behavior.
• Automation. Welcome series, birthdays, abandoned carts: automated emails keep working once they are set up.

Disadvantages of email marketing

• Spam filters. An unauthenticated domain (SPF, DKIM, DMARC) or a poor-quality list stops messages from arriving.
• Crowded inboxes. Your contacts receive dozens of emails a day; without a clear subject line, yours stays unopened.
• Consent is required. The GDPR and anti-spam laws require the recipient's permission: you cannot write to people who never subscribed.
• Production time. Every campaign needs copy and a design that works on mobile.
• List decay. Every year, part of your contacts stop reading or unsubscribe.

Almost every disadvantage can be offset with good practice: double opt-in, domain authentication and regular list cleaning. How to avoid the spam folder.

Is email marketing worth it?
