"High Deliverability, Mixed Bag Customer Service"
What do you like best about SMTP.com?

SMTP.com is a powerful email relay service with excellent deliverability, ideal for businesses sending high volumes of email. However, mixed customer service reviews and higher pricing for low-volume users might deter some. Consider your email volume and preferred support quality before making a decision.

What do you dislike about SMTP.com?

Cost-effective for high-volume senders, SMTP.com's pricing might be high for businesses sending only a few thousand emails monthly. More affordable options exist for smaller volumes.

What problems is SMTP.com solving and how is that benefiting you?

One of the biggest challenges for businesses sending emails is ensuring they reach their intended recipients and avoid spam folders. SMTP.com tackles this by using dedicated, whitelisted IPs and robust infrastructure, boosting deliverability rates.

What do you like best about SMTP.com?

- Ease of use - Scalability - Security features like encryption and authentication protocol

What do you dislike about SMTP.com?

- It seems like they do not offer any trial period in my view, maybe they give it to big players

What problems is SMTP.com solving and how is that benefiting you?

Using this platform ensures the emails are delivered to the recipient's inbox. In that way, the chances are meager that the email will be marked as spam or experience delivery delay.

"Very good experience"
What do you like best about SMTP.com?

It has actually served us well and created us a minimum of 50% of our brand-new company. I send out just 5000 e-mails every 2 weeks, usually without mistake. With every SMTP provider there will be some concerns, it's how you solve them, the support was spot on every time

What do you dislike about SMTP.com?

The only cons I would point out is that the UI has to include some little functions, like password reset for extra accounts

"Best ESP infrastructure and service"
What do you like best about SMTP.com?

Very good infrastructure with white-listing, dedicated sending IPs and in-depth reporting.

What do you dislike about SMTP.com?

We've had a few challenges on sufficient leadtime and notifications on maintenance work by SMTP.com. However, our account manager is in close contact with us to ensure this is not happening again in the future. As SMTP.com is only hosted at one provider, we've had routing issues once. It would be beneficial if SMTP.com would have a second provider in a different country/location.

What problems is SMTP.com solving and how is that benefiting you?

maintaining ESP infrastructure for different accounts with dedicated sending IPs. Centralized support with dedicated account management to easily identify and solve issues. Centralized Reporting and billing.

"Almost Always Dependable and Easy to Use"
What do you like best about SMTP.com?

What I like best about SMTP.com is that I don't have to worry about junky and spammy websites causing the shared IP address to get penalized. That was the most critical factor for me when it came to me choosing SMTP.com over a competitor.

What do you dislike about SMTP.com?

The two main dislikes I have at the moment are that SMTP.com doesn't have a more affordable plan, and it does go down for a few minutes every few months or so, which could equate to lost leads. I don't expect it to have a free version, but a plan for light use would be nice, as I don't think I will ever generate more than 1,000 emails in a month. Overall I don't think anyone can go wrong with signing up and incorporating SMTP.com into their website's tech stack.

What problems is SMTP.com solving and how is that benefiting you?

I am sending out notifications or web form submissions.

"Always delivers"
What do you like best about SMTP.com?

It is easy to set up, secure and gives me analytics that helps me keep my lists up to date. In the years I've been using these guys to relay mass emails, I've never had any difficulty with their service. It just works. Also, their servers seem to consistently stay off the blacklists.

What do you dislike about SMTP.com?

The reporting features are pretty broad, but they could be broader. I would like to download a list of all hard-bounces and all complaints over a given time period in one report, but right now it requires two reports to get all that data.

What problems is SMTP.com solving and how is that benefiting you?

They make sure the bulk email I send for my clients gets delivered. The high deliverability rates are the first step in achieving good ROI on email marketing campaigns. The reports they give me make sure I keep lists up to date and neer spam anyone.

"Reliable service, Great Customer Service, beware if emailing @qq.com"
What do you like best about SMTP.com?

Customer service has been quick to respond and helpful. Set up has been relatively simple and online guides are helpful. We are only testing the system at the moment so have not used the system widespread just yet. We are planning to test the dedicated IP service next. SMTP.com worked smoothly with Filemaker scripts to send emails via SMTP.

What do you dislike about SMTP.com?

Have to pay extra for a dedicated IP address in order to send to @qq.com addresses, because the domain limits the number of emails in a certain time-frame that it will accept from any single IP address. Being in a shared pool of IP addresses meant my single email to a @qq.com address was rejected. If you're planning to do business with China or have any Chinese contacts this will be a concern for you. We have not encountered this issues with other domains as of yet - we are still testing the shared IP address pool at the moment. Online set up guides were out of date, need to be kept current.

What problems is SMTP.com solving and how is that benefiting you?

Our email provider has a 70 email per address per half hour limit. We have hundreds of clients that we need to notify of payments on a single day. We needed a way to bypass that limit. Our database system was also experiencing errors when trying to send via our standard SMTP server, we needed a separate SMTP server to test the issue.

"Good email marketing solution, but customer support is not quick enough"
What do you like best about SMTP.com?

Good email marketing product, good deliverability, with good tracking and reporting for users to understand the email marketing performance. The service performance is reliable and the product is easy to use. Good product recommend to email marketing solution seekers. Worth to give it a try.

What do you dislike about SMTP.com?

Customer support waiting time for oversea users is a bit long, but fair enough and the service is quite reliable, the performance doesn't go down. The only thing not like it now is the pricing is less competitive on the market now. It will be better if the price can go down and provide some free trial services for start users.

"Outright Theft"
What do you like best about SMTP.com?

The service was fine but there's plenty that was not ok.

What do you dislike about SMTP.com?

So for whatever reason, mand I've never run into this with a service driven company. They required 30 days notice for you to cancel. So if one day you realize you don't need the service anymore and cancel you would expect maybe not to get a prorated refund for that month but you would NOT expect to get charged for an additoinal 30 days for the next month, for what? Basically they are stealing an extra month from you. I cancelled on October 2nd so not only did I not get a prorated refund for October (fine) but they wanted to charge me for the entire month of NOvember. Again for what? So I cancelled my credit card so they couldn't charge me. Beware. YOu will always have to pay an extra 30 days no matter when you cancel. 100% theft and very underhanded practice.

What problems is SMTP.com solving and how is that benefiting you?

I used it for SMTP and will never use it again.
