WordPress Mailjet Plugin
Stop your WordPress emails landing in spam
Mailjet is built for reliable email delivery. WP Mail SMTP connects WordPress to it in a few minutes, with no code required.
- Emails that reach the inbox, not spam
- Every WordPress email, automatically routed
- Set up in minutes, no code
- Full email logs and failure alerts

Every WordPress email, routed through Mailjet.
WordPress sends a lot of email: order confirmations, password resets, contact form replies, plugin alerts. By default, all of it goes out through your hosting server, which usually means no authentication, no logs, and no reliable delivery.
Mailjet is built for the job. WP Mail SMTP connects WordPress to it in a few minutes. Every email WordPress sends starts routing through Mailjet from then on, with proper sending reputation and visibility behind it.

Frequently asked questions
Have questions about using Mailjet with WP Mail SMTP? Get answers below. If you need further assistance, contact us.
Do I need WP Mail SMTP Pro to use Mailjet?
No. The Mailjet connection works on the free WP Mail SMTP plugin. Paste your API Key and Secret Key, and your WordPress emails start routing through Mailjet at no extra cost. Pro adds email logs, failure alerts, open and click tracking, and backup connections.
I already use Mailjet. Why do I need WP Mail SMTP?
WordPress’s default mail function sends through your hosting server, not through Mailjet. That means password resets, WooCommerce order confirmations, and contact form notifications skip the sending account you’re already paying for. WP Mail SMTP routes everything through Mailjet instead, so every WordPress email benefits from your sending reputation.
How is this different from using my host’s SMTP?
Your host’s SMTP has no delivery guarantees, no logs you can act on, and shares sending reputation with every other site on the server. If another site gets flagged for spam, yours suffers too. Mailjet is dedicated sending infrastructure with authentication built in, and WP Mail SMTP gives you a full log of every email that was sent or failed.
Can I use Mailjet with WooCommerce, contact forms, and other plugins?
Yes. WP Mail SMTP intercepts all WordPress email at the system level. Once connected, every plugin that sends email through WordPress, from WooCommerce order confirmations to WPForms notifications to membership site alerts, routes automatically through Mailjet. No per-plugin configuration needed.
What sending limits does Mailjet have?
Mailjet’s free tier sends up to 6,000 emails per month with a 200/day cap, and no credit card is required to sign up. Paid plans start at higher volumes with more advanced features. For most WordPress sites, the free tier covers contact forms, order confirmations, and password resets without issue. Check mailjet.com/pricing for current plan details.
How does Mailjet compare to SendLayer or MailerSend?
Mailjet bundles transactional and marketing email in one platform, which is useful if you already use it for newsletters. SendLayer is built by the same team as WP Mail SMTP, with one-click setup and unified support. MailerSend is a similar transactional service with a smaller free tier but a clean API. If you only need WordPress email and want the easiest setup, SendLayer is the lightest path.
