Stay Away from Sparkpost!!

As leofflerg points out you can’t trust them not to suspend you without warning. One of our client’s account was suspended because someone sent a spam link to them using their site’s contact form.

The client tried contacting their compliance team, not really being very technically savvy, they didn’t understand where the spam they were being blamed for came from. After all they didn’t send the spam.

As an agency manager, I reached out to Sparkpost’s compliance once my client notified me of the situation. I just got an automated response saying


Thank you for your interest in SparkPost. We strive to offer the very best email service, and to that end, we maintain a strict anti-abuse messaging policy.

Because we cannot offer you the high deliverability you would expect from SparkPost, we must decline to provide our services. We wish you the best in your future business endeavors.

The SparkPost Compliance Team

So then I tried the head of business development, Beverly Clarke. She connected me with the account manager, Tim Tran. Who politely informed me

I have taken a look at [redacted] and overall looks fine to me. I would continue to try to communicate with our Compliance team and follow their guidance. It would help to figure out how to prevent these links from appearing in your emails or how your system handles outbound email.

I told him about the non-response we were getting from compliance, to which he replied…

I don’t see terminated on your account just yet. But if that’s the only response they’re giving you, we regretfully have to part ways at this point.

It’s some perverse form of digital victim blaming. My client was the victim of contact form spam, and Sparkpost is punishing them for not having done a good enough job of protecting themselves. It doesn’t seem to matter at all to Sparkpost that the client didn’t send the spam or that the recipient of the email was the party they were blaming for sending.

I feel like I have egg on my face for recommending SparkPost to my clients after today. I can’t in good conscious recommend anyone use their service and by proxy this plugin.

Settings gone

Gah! If you deactivate (not delete) the plugin it clears all your settings. There is no warning about this in the settings page or plugin description. I’ve just inadvertently disabled all emails on a live site for the past few hours because of this 🤢

Plugin Settings disappear when deactivated

If you deactivate the Sparkpost plugin (e.g. for testing, bug fixing, etc) then you LOSE all of your settings and your emails then bypass the Sparkpost service without warning.

I was trying to find a fault at my site so naturally deactivated all plugins to figure out the problem. I fixed the problem then reactivated all of my plugins. 3 weeks later through pure chance, I clicked the Sparkpost plugin settings and discovered (to my horror) that there were no settings in there anymore (API key removed, etc) and the ‘send email through Sparkpost’ was unchecked. Not only does this affect my email deliverability but it also LOSES Sparkpost money as emails are no longer routed through their service.

I cannot believe that the plugin settings are not stored in the database or at the very least, there is no admin notification message to warn us that we need to re-enter api key etc when we deactivate/active plugin.

Please fix this!

Good service for little price

We use sparpost for pro service and seriously is great !!!

In fact, as all mail company, if you want a perfect delivery, you need souscribe a dedicated ip for send your mail and parse this sending (type : 300 mail by hour), and all mail are delivered perfectly in box for 20$ by month !

Mail Goes to Spam Folder – Bad Server Reputation

SparkPost says “No One Delivers Better than SparkPost”. Yes, delivered . . . to Spam. The very first test message I ran through the system went straight to the Gmail spam folder because Google does not trust the SparkPost servers. What’s the point?
