Understanding Your SMTP Options
For many just starting out and looking for a free SMTP service to handle their outgoing mail and email delivery needs, Gmail is the default option. Google has a reliable infrastructure that you can count on to stay up and running. While Gmail works well enough for low-volume email delivery, it’s not without its limits. Depending on how many emails you need to send or customers you need to reach in a day, you could quickly outpace Google’s limitations for outgoing mail. And when you do bump up against those limits, your gmail.com account may be temporarily blocked from sending additional outgoing mail – a potential nightmare when those emails matter.
Often Google just isn’t a fit when you need an email service to send at scale. That’s where Mailgun’s plug-and-play email service comes in. It’s incredibly flexible and intuitive. Whether your domain relies on a site like WordPress and you’re looking for an SMTP relay or your developers prefer working with APIs, getting your free SMTP service set up on Mailgun’s SMTP server can be done in a matter of minutes.
Features to Look for in SMTP Providers
Choosing a free SMTP server is important when you’re just starting out, but there are other factors to consider beyond the price tag. Think about whether the third-party SMTP service offers:
Email address validation services to improve your mailing list (because handling thousands of outgoing emails doesn’t matter much if you’re sending marketing campaigns or transactional emails to bad email addresses)
Real-time email tracking and advanced analytics for your emails, so you can track not only sent emails but customer engagement and open rates
Detailed logs to diagnose and eradicate email delivery failures
Deliverability features so you can minimize bounce rates and spam complaints
