I was blocked from the services without notice after paying for tier 5

It seems they have blocked me from using this service, I replied with an apology and to see if we can find out what the problem was so that it can be fixed, but they canceled our account on the first notice without even a warning, after paying for the top tier. Hopefully we can fix the problem and make sure we can use the tool, otherwise, we are still within our 60-day period, so they should at least refund the money. We would rather use the tool.

With that said, the tool is very simple, my client was not pleased with the lack of design templates that are readily available with other providers like constant contact or MailChimp. I convinced them to give this one a chance, but AppSumo seems to have taken their money and cancelled their services. I hope we can fix this.

Confused but I was shocked later

I'm a pretty anxious person, so I gave this service several chances before committing. I even requested refunds twice because the results didn't meet my expectations.
But I've come around — this is genuinely the best newsletter service out there for the price. It's straightforward, fair, and most importantly, it actually delivers emails. Highly recommend it.

Devastated my reach, without telling me

I had 2,300 self-subscribing contacts at the beginning of using this product. Guys who signed up, manually, voluntarily, for the CureCPPS.com emailing list.

I also spent $150 having an expert configure the back end of my domain so that SendFox could send without problems.

Recently I discovered that, about a year after switching to SendFox, they do some sort of "most likely to open" garbage to please Google. "We don't want to get flagged" they say.

Guess how many they sent my critical consultation emails to? Without telling me?

26 out of 2300.

For over a year, my reach, devastated. Why would I expect them to change up how it had worked before? I used to use MailChimp, and that WORKED, but you PAID for it.

I have an open rate that averages north of 50%. Or, I did.

Also, their support team disregarded my messages. They use mailgun and I can't log in.

I've been in business for six years and this might be the worst purchase I have made.

We hear you — the 'engaged only' default was silently limiting sends for too many users. We've already shipped a fix so this is no longer the default behavior. Your full list should now receive campaigns. We'd love for you to give it another try, and please reach out to [email protected] if you need help with your domain setup.

Allow Transactional Emails Please

I got Tier 1 specifically to try the API integration. While the interface is clean, the API itself is far too restrictive for a complete setup. It currently lacks the hooks needed for basic transactional triggers like password resets, which makes it hard to use as a primary tool. I’d love to see the API expanded to handle these use cases; once that’s implemented, this would easily be a Max Tier product for me.

Thanks for the feedback! We've recently expanded the API significantly with better documentation and more endpoints. That said, SendFox is designed for marketing email (newsletters, automations, campaigns) as we've mentioned clearly in reviews, the Q&A, and From the Founder area rather than transactional email like password resets — tools like SendGrid or Postmark are better suited for that use...

Customer Service doesn't bother anyone

I was very happy for a long time. But now I must say... it's getting worse.
Forget about asking support for any help.
They don't bother to respond anymore...

We're sorry about the support delays. Looking at your account, it looks like Garry followed up with a couple times — and our HelpScout read/open tracking shows that it was seen. If you're still having issues, please email [email protected] and we'll prioritize it as quickly as we can.
