Here’s a common problem: You send out a confirmation order email or a newsletter through your website hosting provider’s email server, but unfortunately hardly any contacts receive the message. That's a particular issue with self-managed newsletter software like Supermailer, Sendblaster, or with WordPress plugins such as Mailpoet.
Why does this happen?
Well, there are two underlying problems here. For starters, most website hosting providers have very strict sending limits in place. Companies such as 1&1 or GoDaddy radically limit the amount of email traffic permitted on their servers. 1&1, for instance, will allow no more than 30 emails in 5 minutes. If you try to send out more, the provider will cut you off, and you won’t be able to send anything at all.
And that’s not even the main issue.
Due to the amount of junk and spam sent via email, email services such as Gmail, Outlook, and Yahoo don’t allow messages from unknown servers – it’s that simple. Such emails will either turn up in your spam folder, or worse, never reach your inbox at all.
During our tests using Mail-Tester.com, this was, sadly, often the result:

Gmail, Outlook, Yahoo, and similar services just don’t trust email servers without a whitelist entry. What they want is a good sender reputation – and that’s not easy to come by. At least not if you try getting that reputation on your own.
All you need is a good email server, also known as an SMTP relay. There are a few providers suitable for both transactional emails (order and registration confirmations, invoices, and other notifications) as well as mass emails (e.g. newsletters). These tools are more generally known as mass email services.
Typically, you would create the email in a different system, like your CRM, CMS or invoicing software, and connect the mass email service to deliver the messages.
Here's an overview of the features and pricing of a few providers:

MailerSend is the transaction email service from MailerLite, a newsletter service we rate very highly. If you’ve used MailerLite then you’ll know it’s a really easy-to-use tool with a modern interface and fast email builder – MailerSend is no different. In fact, the builder looks much the same. We’ve seen very good deliverability results from MailerLite, and don’t doubt that MailerSend’s would be just as good.
The free plan lets you send 12,000 emails /month, and if you send more than 12,000, the cost of additional emails is $1.00 per 1,000 emails – that’s not bad at all! Plus, there’s no daily limit, like there is with a number of other services on this list.
Mailjet is one of the more affordable newsletter software providers on the market, offering users 60,000 emails for just $18.95. Aside from transactional emails, you’ll also get a drag and drop email editor, simple automation, SMS and A/B testing. Our deliverability tests show that Mailjet really takes its deliverability seriously.
It claims it can send up to 15M emails/hour via its email API, even during peak sending periods.
Mailjet supports 80 integrations including ecommerce platforms, CRMs and Facebook.
Sendinblue covers a host of services: marketing automation, email campaigns, transactional emails, SMS messages, chat, CRM, Facebook ads and more. We rate it pretty highly as an email newsletter service due to its reasonable prices and comprehensive offering.
It has a nicely-featured free plan, which includes marketing automation, phone support (for the first 60 days) and up to 300 emails per day. This daily limit might impede your activity – I’d advise avoiding limits of this kind for sending transactional emails.
If you want your own dedicated IP, you’ll need to sign up for the pricier Enterprise plan.
Mailgun is Mailjet’s sister service, in fact, parent company Pathwire acquired both Mailgun and Mailjet. There are even plans to merge both in the future. It’s directed to developers who want to set up powerful APIs, and it promises an impressive deliverability rate of 97.4%.
Mailgun offers a Flex account, which gives you 5,000 free emails per month for 3 months, after which you’ll only pay for what you send at $0.80 / 1000 emails.
Sendgrid is a mass email service for sending marketing email as well as transactional emails. With a limit of 100/emails/day, Sendgrid’s free plan isn’t quite as generous as the other providers’. However, its paid plan starts at a reasonable $14.95/month for 100,000 emails.
This comes with delivery optimization tools, a dynamic template editor and analytics. Unfortunately, you won’t have access to email validation unless you shell out $90/month for its Pro plan.
Pepipost, a cloud-based bulk email service, claims to ‘reliably deliver 10 billion emails a month for over 50,000 customers’. That’s a lot of email!
It uses AI technology to improve deliverability and allows you to send bulk emails with open source email marketing platforms Mautic and Mailtrain.
It comes with a free plan, though after the first 30 days, this becomes quite limited.
You will also get real-time reports, so you can see exactly how your deliverability is doing. Dedicated IPs are available at a cost of $20 per month.
24/7 live chat support is available, though only in English. The company belongs to Netcore, a Mumbai-based marketing software.

Amazon SES is a good choice for those using the web service Amazon Elastic Compute Cloud (Amazon EC2), as you get 62,000 emails for free each month. If you’re not, there’s no free plan, but at $0.10 per 1,000 emails, it’s not too expensive.
If you’d like a dedicated IP address, it’ll cost you $24.95 per month.
Unfortunately, it’s missing A/B testing, list management and spam testing.
Postmark is a dedicated transactional email service, which, unlike Mailjet or Sendinblue, doesn’t cover email newsletters. This isn’t necessarily a bad thing, but it’s something to be aware of, as you’ll need to use another service for that. What it does offer are responsive templates for order receipts, password resets, etc., and, of course, you can create dynamic templates by editing the HTML and CSS.
The interface is modern and easy to navigate, and the pricing is made simple by including all features – you simply pay for the number of emails you need.
Firstly, in order to use this service you must hold a Mailchimp account.
Mailchimp Transactional Email is offered only as a paid add-on to a Mailchimp Standard or higher account. However, those on the free plan can activate the Mailchimp Transactional demo, which gives you up to 500 emails for free. Note that this is only available if you’ve a new user of Mailchimp Transactional.
As a paid add-on, you’re looking at paying $20 per 25,000 emails, though the more you buy, the less you’ll pay per email.
You can add a dedicated IP for $29.95/month.
Even though you can theoretically send emails for free by using your own website hosting provider, that's usually not a good idea. (SMTP) is the much better choice for sending transactional and bulk emails. Many mass email services have an unlimited amount of time, so you can rest assured that your emails will get delivered.
