No Longer a Deal

Used to love Sendfox. Recommended it to many clients who purchased directly and a few who purchased through us. Minimal branding I'd be ok with but once paid it should be absolutely minimal. More importantly, having to pay a monthly subscription goes against everything AppSumo stands for - to remove branding and change double opt in. Very disappointed. (Lifetime equals MailChimp free now, just more contacts.)

not working now

I started using this product 2 months ago. I was impressed by the start campaigns it created however I created my newsletter in a different style. Since one day it's not working, I can not add images and my last newsletter was not even sent nor saved. I am quite in a shock, not having yet heard from them.
I wish the newsletter design will be more modern allowing boxes and images closer to printed magazines. I would appreciate to have more creative choice with that.
It would be nice if they implemented also a subscription affiliate partnerships among the magazines.

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...
