Which is the Best SMTP Service Provider?

The high number of options make it difficult for users to choose the very best SMTP service supplier for their needs.

When choosing an SMTP support, you have to look in three chief factors: email deliverability, scalability, and pricing.

Since each platform in our list offers high email deliverability and with exclusion of G Suite and Office365, all platforms can scale to send tens of thousands of emails per day, we will concentrate on pricing since it’s frequently a large deciding factor.

At first glance, the free programs look very competitive across all platforms. If you have a website, then you really can’t go wrong with any our top two SMTP recommendation: SendinBlue, and Mailgun.

However as your website grows, pricing becomes a pretty big element. SendinBlue supplies the most competitive pricing using most importantly reliable and scalability support.

By way of instance, if you are sending 120,000 emails per month, you may pay $66 a month, and you will have a dedicated IP. Except for the same amount of sending requirement and committed IP, SendGrid will price $79.95 per month and MailGun will cost $109 a month.

Now in case you’ve got a specialized team in home, then nothing will beat the prices of Amazon SES since its $0.10 per 1000 emails. This means 120,000 emails per month is only going to charge $12 on Amazon SES. The big advantage is that their support is limited. For dedicated IP, you just have to pay $24.95 a month.

For large sites, there really isn’t a more cost efficient SMTP alternative than Amazon.
