User-friendly, exceptional email tracking and proof of delivery,
I didn't find anything that I don't like about SMTP2GO
Rating: ⭐⭐⭐⭐⭐ (5/5) As an academic institution, we rely heavily on email communication for various administrative and educational purposes. Over the years, we've tried several SMTP services, but SMTP2GO stands out as the perfect solution for our needs. SMTP2GO offers a seamless and reliable SMTP service that has significantly improved our email delivery rates. We no longer worry about important emails being flagged as spam or not reaching their intended recipients. What sets SMTP2GO apart from other SMTP services is its exceptional email tracking and proof of delivery features. In an academic environment, accountability and evidence of email communication are crucial. SMTP2GO provides detailed delivery reports and real-time tracking, ensuring that we have a record of every email sent. This feature has been invaluable for us when dealing with student communication. SMTP2GO's user-friendly interface makes it easy for both technical and non-technical staff to access and understand email tracking data. This accessibility has improved our transparency and helped us resolve any email-related issues promptly. No complaints about customer support Overall, SMTP2GO is a great product.
As an developer for a plansystem for service companies we are sending 10k e-mails each month. Delivery succes is extremely high. Via the API everything can be configurated. Because of that it's easy the implement in my webapplication. Also the webhook is showing a lot of tracking information. Based on templates it's easy to send bulk e-mail. If you have a question the live chat support is fast. You will get response during the day almost immediatly. One word: Great!
Easy integration with Plesk. You need to verify senders to send your messages spam free, but it's a lot of work to change all DNS settings for it, if you have a lot of domains as senders.
We other service we had a lot of problems with gmail, hotmail/live addresses. The customers of my client have a lot of users that uses that kind of e-mail addresses. A lot of emails got in to the spambox. Now using SMTP2GO for almost 3 years without any problems of sending emails
SMTP2GO is a lot better than my singing. My story starts like this - I run a nonprofit matching service that connects Carehome residents with volunteers who wish to send them a small letter or gift for Christmas. There are 100's of Carehomes that are state funded and run but also 100's of private locations. Email interaction with the Carehomes and Volunteers is paramount. Last year I discovered , that the service I was using ( not SMTP2Go at the time ) , had servers that were blocked by the State Carehomes. It was embarrasing , because we had over 1K emails go out to carehomes but none of the state homes received them - and so didnt register with our service. I discovered this in time , and quickly switched to SMTP2GO. The setup is easy ( verifying is a bit tricky if you arent technical , I am. ) and i could see emails pump through the system. In all 24K emails were sent and the bounce rate was very low. The SMTP2GO system told me easily , using the filters , which didnt send. I was able to manually follow up on "bad emails". I dont often write reviews - but these are good guys. I have a Starter 10K account with them now , I use this for various other groups Im responsible for . Their support is quick and easy to access too.
Verifying your domain is a little tricky if you arent technical . This isnt really a SMTP2GO issue , more of a DNS setup thing.
I need to make sure email is delivered. Simple !
Used by our Exchange Server. Sage 50, Sage Payroll and different spects of our ERP system under diffeent account headings for detailed analysis
There does not appear to be an option to extend the history so we download the transactions on a monthly basis
It works, causes no problems, is easy to query and halp to track mail
When a customer of my website services reported issues with delivery failures on their emails, I had to find a flexible and cost-effective solution quickly. I started looking at the issue with the intention of solving this by cleaning up their email status. When I spoke to a friend in the hosting industry, he recommended SMTP2GO. I quickly scanned their website and signed up on the spot. The whole process was painless and allowed me to provide a reliable service to my customer while being able to use the service myself. I would highly recommend this service as cost-effective and reliable. I am now offering this option to all of my customer base as an upgrade to my web services.
Hmmm nothing comes to mind, I have never had an issue
Issues with customer email delivery
As our company is providing both email accounts and voicemail to email, using a service that we can rely on a daily basis was our priority. We tried other solutions in the past from our own infrastructure to competitors, but the bottom line was that SMTP2GO was able to deliver both our email and voicemail to email 100% of the time. Never had an issue and we are sending 1000's of email per month.
SMTP2GO a few years back had minor issues with bounce back emails but we were able with the help of support to rapidly find a solution that still work today. As we were using the service to deliver email from a cPanel server, we had to change a few line of code in Exim but the tutorials were very helpful in the end.
We were looking for a solution that could prove that the email was delivered, then if it was read or not so using the portal at SMTP2GO to help our customers validated the delivery of emails.
The control panel is intuitive and the support is outstanding. Pricing is also good with a very genrous free plan.
Nothing it; s agreta product does what it says on the tin
It allows me to easily configure multifunction printers to scan to email. Is is also usefu lfor bulk mailing invoices without getting blocked.
I've used SMTP2GO for years now without ever having any problems. They have done a great job at making a dependable service. Wish more companies would do the same.
Honestly, I can't think of one downside to using SMTP2GO, I've thought hard about this even trying to pick on some small aspect and can't find anything, they're just that good.
I needed a bulk email provider as well as transaction based email provider for my apps on the App Store so that my customers can reach me. We needed to send thousands of emails a month.
The tool provides good status on why emailed failed as well as those which succeeded, it is a very reliable service
the interface is this very basic, the UI could enjoy a major upgrade
permitting the bulk emailing of statements to members. gives an audit trail of successful mail outs,
After trying several tools, some very complex and others too expensive, after finding SMTP2GO I found all the features I needed. The free plan is quite decent, the paid one is spectacular, I can connect the SMTP service with any external APP in a simple way, and better, I can separate it by domain or even create subaccounts to better manage each user.
I still haven't found any reason to submit a review, I've been using the paid service for a few months now and I've connected to about 5 external APPs without any problems.
It makes it possible for emails to be triggered in the applications I have without falling into SPAM, of course I have to have the list checked and ensure that users have the possibility of unsubscribing.
