Totally reliable email delivery!

I've been using SMTP.com for a while now for my transactional emails, and they just work! The Transactional Email API was super easy to integrate into my application. Deliverability has been consistently high, and I haven't had any issues with emails getting lost or delayed. It's a huge relief not to worry about email infrastructure. I'm definitely sticking with them and tell my colleagues about it!

Solid service, few minor points

I recently switched to SMTP.com for my business's email infrastructure, specifically using their High Volume Email Sending. The initial setup of SPF and DKIM was pretty clear with their documentation, but I did need to contact support once for a quick clarification on a specific DNS record, and they responded within a few hours. The Email Logs are really helpful for debugging, and the real-time analytics give a good overview of our campaigns. Delivery has been very good, which is crucial for us. My only small gripe is that I wish the sub-account management interface was a tiny bit more intuitive, but overall, it's a robust service that does what it promises.

Easy to get started

I needed a new email service for my small business and stumbled upon SMTP.com. Signing up for the free trial was straightforward. I just used the SMTP Relay Service, and it worked as expected. No fuss, which is exactly what I wanted.

Consistent performance, as always

This isn't my first time using SMTP.com. I've had their Dedicated IP Addresses for over a year now, and the service remains consistent. My last order was for a slight plan upgrade to accommodate higher volume, and it was handled efficiently, just like previous times. It's good to know I can count on them for reliable email sending without any surprises.

Good value for features

I was comparing a few email providers and saw that SMTP.com offered a decent free trial, which helped me test it out without commitment. The annual billing discount was a good incentive to commit, saving me a bit of money compared to monthly. For the features, especially the Email Tracking and real-time analytics, it felt like a solid investment for the price.

Thinking of switching over from Mailgun. Is SMTP.com actually better for deliverability, or is it pretty much the same deal?

E Emily White 3 weeks ago
I moved from SendGrid last year. Honestly, my open rates have been pretty consistent, maybe a tiny bit better. Their reputation defender thing seems to help though.

It's hard to say 'better' across the board, depends on your use case. But I've found their support to be quicker and more helpful than Mailgun's ever was, which makes a big difference if things go sideways.

Is there usually a promo code floating around for new sign-ups, or is it mostly just the free trial they talk about?

D Donna Clark 1 month ago
Mostly free trial. I've only ever seen codes for specific campaigns, like maybe through a partner link or something special.

Yeah, I signed up a few months ago and only saw the trial. Didn't come across any discount codes when I was looking.
