### "Does not work - Wasted Money"

June 18, 2024

1.0

Customer service was bad. Implementation was difficult. Cost is expensive. Delivery is not reliable.

Pros

absolutely nothing. waste of my time and money.

Cons

I was with this company for almost a year and all of my emails went into junk folders. I have other emails with other providers and the success rate was so much better. I never sent out more than 50 emails a week, so it was ridiculous that SMTP servers were sending my emails to junk. When I asked for guidance, their help team said I should address my emails with "Mr. or Mrs.". That's how clueless this company is. Americans don't use that salutation.

### "Good but not perfect"

April 17, 2023

4.0

Deliverability is really quite good - and this is always number one for me. However, if someone has a limited budget, they probably will find other services on the market with similar parameters for a lower price (or better services for the same price). I did just that.

Pros

SMTP.com is a solid brand, a mature company with a stable position. Its biggest advantages are definitely good email deliverability (although not perfect).

Cons

The amount of features is as expected, but setup is not so easy. The interface is often confusing and somewhat dated. It's worth to do something with it, dear SMTP.com :)

### "Be careful of autorenewal trap!"

August 21, 2024

1.0

So the renewal kicks in automatically. No email is sent that renewal will kick in. You are expected to remember that there is 30 days notification required. So the payment is taken, I then cancel, realise I do not use this service. SMPT says because you did not give us 30 days notice we will charge you for a whole year. I have canceled as not using it! SMPT enjoy 11 months of my money when I'm not even using it!

Pros

The service is good when you have need of it. But they trap you with autorenewal.

Cons

Poor service if you want to leave SMTP. Just just cite you did not give 30 days notice. Go elsewhere.

### "Good but Costly Service "

June 21, 2022

5.0

If your business depends more on the transactions emails with huge customer base then I would recommend SMTP

Pros

SMTP is an good service with high deliverability for the transitional emails. They also provide the sandbox for the students and startups. As the have an high security measure for the account holders, it help to keep our sending server clean

Cons

Seems too costly in comparison with any other email relay service providers
