SMTP2GO in More Detail

WordPress Plugin

This year, we have rolled out our very own WordPress Plugin! It’s easy to set up and has had raving reviews so far.

Our Support Team

The support team here at SMTP2GO is definitely worth a second mention. They are a mix of Brits, Americans, Irish, and Kiwis who also offer support in Spanish. You will always find a support agent online and can expect a timely, knowledgeable response. We know how frustrating it can be waiting for advice or support, so it was extremely important for SMTP2GO to invest in a top-notch support team. You can contact them 24 hours a day via our live chat, by opening a ticket, or over the phone.

Our Review Team

As well as our support team, we have a dedicated review team to ensure that our IP addresses remain off those blacklists. If, by some chance, the IP address you are using becomes blacklisted or similar, we will switch your email traffic over immediately. It is very important for us to keep the reputation of our IP addresses which is why we maintain extensive and strict terms of service. 

Worldwide Servers

By using special routing technology, you will automatically connect to the closest server (geographically), which is great for sending speed. If you are located outside of Europe but would like your emails to be sent via our European servers; then you can request to switch permanently to send via our Amsterdam data centre. This will come in handy when the General Data Protection Regulation (GDPR) is officially introduced. We also have a number of US-based servers; therefore, if you are based in the US and want your emails to remain in the US, job done.

How Much Does it Cost?

There are a variety of plans available at SMTP2GO which are based on the number of emails you would like to send per month. All plans from 100,000+ emails per month come with a dedicated IP and access to our email testing feature. To find out more about the plans we have available, please take a look at our pricing page.

What Do Our Customers Have to Say?

Helen Anderson, Trustpilot

“We’ve tried SendGrid and a few other ‘market leaders’, however, SMPT2GO was the only mail sender that worked 100%. Excellent product, easy to set-up, easy to govern and edit and excellent support. Absolutely thoroughly recommended – price is also extremely fair.”

Greg B, G2Crowd

“Fast, reliable, good features. I set it and forget it. SMTP is not something you should need to think about on a daily basis and SMTP2GO makes that happen with a service that just works correctly. Nice portal and fast customer service.”

Ken Richardson, Capterra

“No drama, ever!”
