Email Marketing Benchmarks in Vietnam

The average email open rate in Vietnam is around 15.1% across all industries — lower than mature markets like the USA or Germany. This reflects a combination of less established permission-based email culture, higher spam filtering rates, and lower Apple device penetration (which inflates open rates via Mail Privacy Protection). Click rate is a more reliable engagement metric in Asia Pacific because it is not affected by MPP inflation.

Email open rates in Vietnam are lower for several reasons: higher spam filter aggressiveness in local ISPs, lower Apple Mail usage (so less MPP inflation), busier inboxes due to less permission-based email culture, and less email marketing sophistication in local senders meaning recipients receive more irrelevant emails. Improve Vietnam open rates with localised subject lines, sending at Asia Pacific peak engagement times, and building a double-opted-in list rather than purchasing contacts.

The average email click rate in Vietnam is around 2.0–2.4% (clicks ÷ delivered). Given that open rates in Asia Pacific can be unreliable due to lower Apple device penetration, click rate is the most actionable metric to track — it is not affected by Mail Privacy Protection inflation. A click rate above 3% is a strong result for Vietnam campaigns. Mobile optimisation is critical — the majority of email opens in Asia Pacific occur on mobile devices.

The average email unsubscribe rate in Vietnam is around 0.22–0.28% per send — slightly above mature market averages. This often reflects less established list permission practices in Asia Pacific. High unsubscribes in Vietnam are typically a sign of purchased or scraped lists, irrelevant content, or sending to contacts who did not actively opt in. Using double opt-in and cleaning inactive subscribers every 6 months will bring unsubscribe rates down significantly.

For eCommerce businesses in Vietnam, Klaviyo is the strongest option for Shopify integration and revenue-based segmentation. Mailchimp and Brevo (formerly Sendinblue) offer good value for small-to-medium businesses in Asia Pacific. For B2B, HubSpot and ActiveCampaign provide CRM-integrated email workflows. Ensure your chosen platform supports Asia Pacific timezone optimisation and has good deliverability in Vietnam — some platforms have stronger local ISP relationships than others.

Benchmarks are reviewed and updated quarterly. The current data reflects industry aggregates compiled from anonymised campaign data and published industry reports. Individual results will vary based on email platform, list quality, send frequency, content relevance, and subject line quality.
