Frequently asked questions

How do transactional emails differ from marketing emails?

Transactional emails are triggered by user actions and contain information specific to those interactions, like order confirmations or password resets. Marketing emails are sent to promote products or services, including newsletters and promotional campaigns, and target a broader audience.

What steps can I take to improve the deliverability of my transactional emails?

To enhance deliverability, use a reputable email service provider, maintain a clean and updated email list, authenticate emails with SPF, DKIM, and DMARC, avoid using spammy language, and regularly monitor email performance and metrics.

Are transactional emails subject to anti-spam regulations?

Yes, transactional emails must comply with regulations like the CAN-SPAM Act in the US and GDPR in the EU. Although they are not primarily promotional, they still need to include accurate sender information and provide recipients with an easy way to opt-out of future emails if applicable.

Is it permissible to include promotional content in transactional emails?

While the main focus of transactional emails should remain on the primary message, it is generally acceptable to include subtle promotional content, such as cross-sell or up-sell suggestions, provided it does not overshadow the main information and complies with relevant laws.

What factors should I consider when choosing a transactional email service?

When selecting a transactional email service, consider factors such as the service's deliverability rates, pricing, ease of integration, scalability, customer support, and the specific features that align with your business needs. Comparing multiple providers can help you make an informed decision.
