The best free SMTP email services you should use

SMTP Server (the server used to send mail) is a service that allows sending emails in large quantities, fast speed without limitation such as free Gmail mailboxes or mail attached hosting.

I personally prefer to use external SMTP Server services, the first is to reduce the load for Web Hosting / Server due to not having to send the email anymore,

And the second is because of Shared IP or Blacklist due to spam users The mail is bluff, so the outgoing mail is flown into the Spam section (you don’t spam mail but other people using the same hosting spam should be affected).

Best free SMTP email services


Some providers only have SMTP Server (or transactional email) services, but there are also vendors that support comprehensive email solutions by adding the Email Marketing service.

All current SMTP Server Email service providers will usually have free and paid packages. The free plan will be limited to sending mail by month, by day or limited features, while the paid package will be more comfortable. 

Depending on your needs, please refer to the Free and paid upgrade packages to choose dental services.

1, Mailgun

Mailgun allows sending 10,000 free emails per month, from the 10th, 2001 email onwards, priced at $ 0.50 / 1,000 emails. This is a service provided by Rackspace, the main user is developer with a rich API library.


Mailgun also has a validate email service, which allows checking email addresses for errors. The free package is allowed to check 100 mail addresses/month, beyond this you have to pay extra. If you use the SMTP mailing service, it is not necessary to check.

Mailgun has full tracking statistics (open, click, delivery time …), supports inbound routing, dedicated IP with the official plugin for WordPress.

New accounts are limited to 100 mail/hour if the delivery rate is goodwill remove this limit. In addition, Account Free can only be sent to emails that agree to receive mail (Authorized Recipients), so this account is almost useless. You need to upgrade your account by adding more card information, there will be no need to pay if the number of emails sent each month <= 10,000 mail, exceeds the new fee will be charged.
