SMTP Relay

• Global Server Network: With servers across the US, Europe, Asia, and more, SMTP2GO automatically connects you to the nearest server for fast, reliable delivery worldwide.
• Customizable Sender Domains: Verify your sender domain to send from any address at your domain, building trust and boosting inbox placement with proper SPF, DKIM, and DMARC setup.

Powerful API for Developers

• Flexible Email Sending Options: Choose between the Standard Email endpoint, where you send email components (sender, subject, body) as a JSON object, or the MIME Email option, where you send a fully formatted email using your preferred tool. SMTP2GO handles the rest.
• Seamless Integration: Developers can easily add email and SMS features to their apps using simple endpoints like /email/send, /sms/send, and /template/add. These work smoothly with different programming languages, making the process hassle-free.

Email Tracking and Analytics

• Comprehensive Insights: Monitor email events like deliveries, opens, clicks, bounces, and unsubscribes with detailed, real-time reporting. Search by sender or recipient for pinpoint accuracy.
• Performance Optimization: Use this data to refine campaigns, improve targeting, and boost engagement—know exactly what’s working and what’s not.

Deliverability Optimization

• Inbox Placement Tools: SMTP2GO’s global infrastructure and reputation management tools help your emails land in the inbox, not spam. Monitor your sender score and avoid blacklists with proactive alerts.

SMTP2GO Pros and Cons

SMTP2GO is a powerful email delivery service designed to help businesses ensure reliable email sending with high deliverability rates and global server coverage. 

It offers a seamless setup, real-time analytics, and easy integration with various platforms, making it a go-to choice for those who need a dependable email-sending solution.

However, like any service, SMTP2GO has its strengths and limitations. Below, we’ll explore the key pros and potential downsides to help you determine if it’s the right fit for your needs.

SMTP2GO with WordPress for Sending Your Emails

If you’re a WordPress user, you may have encountered frustrating email delivery issues—emails not being sent, landing in spam, or completely disappearing. 

This happens because WordPress uses the default wp_mail() function, which relies on PHP to send emails. Many web hosts aren’t optimized for this, leading to unreliable email performance.

But don’t worry—there’s a solution!

Select FluentSMTP for a Better Solution

Integrating SMTP2GO with WordPress ensures that your emails are sent through a reliable SMTP server instead of PHP mail, significantly improving deliverability. To make the setup seamless, you can use an SMTP plugin like FluentSMTP which works effortlessly with SMTP2GO.

Key Benefits of Using SMTP2GO with WordPress

• Reliable Email Delivery: SMTP2GO ensures that all emails from your WordPress site—whether contact form submissions, order confirmations, or password reset emails—reach inboxes without fail.
• Avoid Spam Filters: With proper SPF, DKIM, and DMARC authentication, SMTP2GO enhances your domain reputation, reducing the chances of emails being marked as spam.
• Works with Any Hosting Provider: Whether you’re using shared hosting, VPS, or a dedicated server, SMTP2GO ensures consistent email performance without relying on your host’s email infrastructure.
• Global Email Infrastructure: SMTP2GO has servers worldwide, providing redundancy and reliability, so your emails are delivered faster and more securely.
