SendFox Reviews

UPDATE! 6-16-2026
Support Came Through For Us

I want to update my previous review with what happened after I posted it.

After reaching out to SendFox support about the HTML editor issue, their Customer Experience Manager Luka followed up personally, acknowledged the problem, and restored HTML editing access to our account. We tested it immediately and our full custom HTML template rendered perfectly.

The initial experience was frustrating, especially as a brand new customer who purchased just days before the change. But the way our issue was handled, with honesty, a personal follow-up, and a real resolution, reflects well on their support team.

I can only speak to our own experience, but for us they made it right.
That counts for a lot. FIVE well earned tacos!

Original Review:
We purchased SendFox through AppSumo for our non-profit Raiders booster club and used it successfully to send our monthly newsletter and occasional announcements to our members.

The HTML editor was a key feature we relied on to create branded, professional-looking emails. It worked well and allowed us to maintain a consistent look and feel that represented our club properly.

Recently the interface changed completely. The HTML editor no longer functions the way it did. When we paste our custom HTML code, the styling does not render correctly. Background colors are stripped, text content disappears, and the layout breaks. What used to work now does not work.

We have contacted SendFox support and are waiting to hear back. But as it stands, a feature that worked when we purchased the product no longer works. For a club that depends on clean, professional email communications to stay connected with its members, this is a significant problem.

We hope SendFox resolves this soon. Until then, we cannot recommend the product in its current state.

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.)

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.

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.

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.
