It is almost impossible to have your business grow and get more clients and income without using the benefits of email marketing.

Thus, the great solution for you is outgoing mail server. These are the services offered by several companies, which are great tools helping you to send emails not overloading own resources and the most important – they free up your time!

But why not to create own SMTP server? First of all, growing business will be in need to send more emails, on personal SMTP server you will be limited to 400 daily. Also you will be limited on emails daily or hourly and limits depend on your host, even if you  run dedicated server! Also you will not have an option easy to whitelist yourself and not be labeled as spam.

Mailgun

It has pretty simple pricing, where you need to signup and start sending mails as many as you want. In case you send less than 10000 monthly – you will be on free plan.

SMTP Providers Pricing Comparison

Check free monthly plans and have a try using the free plan to check cooperation with any of providers:

  • Mandrill has a free trial with no limitation on the number of emails sent.

Marketing Emails

If marketing email sending is absolutely a key point – please acknowledge that marketing emails are offered by SendGrid and Mailgun, while Mandrill doesn’t have such a function. On the other side, all 3 providers offer transactional emails, which are sent to your clients upon their registration, purchase or any other actions on your site. All providers offer API and admin panel with extensive logs stats on mails.

Supported Technologies

What should you pay attention to – is supported API languages, as it may be the key point in your decision with the outgoing mail server. All providers support popular PHP, NodeJS, Python, Ruby. But Support of C# and Java is offered only by SenGgrid and Mailgun. Javascript is supported solely by Mandrill. SendGrid is proud to offer Go support, while Luvit, cURL is offered solely by Mailgun.

Volume Limitations

As you may have noticed, all providers offer practically the same services, having minor peculiarities. What else you need to pay attention to? All of them have limitation on number of emails:

  • SendGrid limits daily number of emails: not more than 1000 emails daily and 7 day limit – 10,000 emails.
  • Mailgun has a limit of 1000 mails during a single API call
  • Mandrill has a fixed number of emails per hour depending on your average volume and reputation.

A small notice about SPF notes: For Mailgun and Mandrill – they are mandatory. For SendGrid – optional, but you need to verify your sender IP then.

And the last, but the most important for you: spam complaint handling! Solely Mandrill offers no option to deal with it.
