List of Email/SMTP providers

Yes there are many others.

Here's a list I've compiled over the years with some of my notes.

==========
List of Email Deliverability Services Like SendGrid and Amazon SES

https://postmarkapp.com/
Very expensive. 10 x more than Amazon SES.

Transactional Email from MailChimp - Mandrill
The parent company is MailChimp. But this seems quite inexpensive. Possibly even cheaper than Amazon SES considering you can get a dedicated IP Address.

First 12,000 emails per month are free.

https://www.smtp.com/
Quite expensive - $500 for 500k emails a month. Amazon SES would be $50 for that amount of emails. Or 10x more expensive.

Marketing & Transactional Email Service | SendGrid
Quite good but on the pricey side. Though they have a discounted plan for transactional emails. But far from ideal.

$424.95 a month for 500K emails.


http://www.socketlabs.com/
$449 a month for 500K emails.


http://www.mailjet.com/

6000 emails per month are included free. But seems pretty expensive overall.


http://elasticemail.com/
Can get much cheaper over time as you send more and your reputation stays good. Can even be lower than Amazon SES. Now cheaper than Mandrill.

This may be another Amazon SES competitor in terms of price.
emailocean.com
However they are located in India and their English is certainly not perfect. A small time operation at the present with an Alexa Ranking of 3,646,024. Even the menu bar links on their website do not work properly. (Site seems to be down 6/27/15)


Email Delivery | Transactional Email | Inbox Delivery | Dyn

Transactional Email API Service for Developers by Rackspace - Mailgun
A bit cheaper than Sendgrid. $145 for 300,000 emails per month instead of $199. However with dedicated IP it costs a bit more at $204 per month. $245 for 500,000 emails sent per month. Quite pricey but not the worst.

First 10,000 emails per month are free.

http://www.jangosmtp.com/
Nice looking colors at the header of the website. (Seems like it's only for transactional emails and is super expensive.)

Homepage | EmailDeliveredEmailDelivered
Plans starting at too high for my needs. Expensive.


http://www.drh.net/greenarrow-engine/
I don't know the pricing yet. I'd need to call them up.

Turns out they focus on people with HUGE email lists. They can deliver over a million emails per hour with their enterprise level. And up to 100,000 emails per hour.

If you had a huge list these guys would be quite inexpensive.

This company uses the green arrow mta but does a hosted service.
Pricing | Elite Email



http://aws.amazon.com/ses/
10 cents per thousand emails. 500K would be only $50 a month.


https://serversmtp.com/en/cart.php?systpl=turbo-smtp
500K = $310 a month plus your own IP.

http://www.unifiedemail.net/Service/SMTP-Relay/
500K = $365 a month.

I am creating an smtp site that offers similar website, could you list the free ones so that I get it boosted at the start.

or the websites that would enable me to sell their email to my clients

I can add (pardon me if these were mentioned before)
Mailrelay
bulkresponse
TEARcloud
sendpulse

AmazonSES seems to be the father of all. Their service is very cheap and it connects seemlessly with alot of apps.

Pricing and the ability to test the SMTP before making a purchases are 2 big factors we considered. Check out our service TEARcloud.com and send up to 10k free emails / month.
