As a long-time user and recently…

As a long-time user and recently onboarded Mailchannels fully to my web hosting business, I have had a really positive experience. Support is fine; it could be a bit faster, but when the niche is critical, they respond fast, which is what matters.

We switched from Spam Experts to Mailchannels for outbound checks, and honestly, all the issues disappeared. Mail was consistently sent, and we received no complaints from clients. Even during migration, since we set it up correctly with their help, clients didn't experience a single email of downtime, which was great.

I used it for the past four years on my personal inbox, and now that I migrated to the hosting business for my clients, I am very satisfied with everything, so good job team. Please keep up the good work.

If you continue to improve the service with some minor adjustments to the signup process and the panel, the product will be even better.

Overall, I'm satisfied and would love to see how it goes in the long term. I believe they will improve it. The price is fine; they did raise it recently, but while I'm not impacted yet, hopefully, I won't be.

Worst email filtering service

Easily the worst email filtering service currently in operation. Literally worse than useless.

Since Dreamhost made the mistake of switching to Mailchannels, the number of spam email and especially phish email I've received has skyrocketed. Phishers love Mailchannels, because it's incredibly poor at detecting phish emails. A well-organized phish ring targeting Dreamhost has been active since almost the day Dreamhost started using Mailchannels.

Mailchannels relies on AI to spot scam and phish emails, but their AI is terrible. It's so bad it even allows old-school Nigerian 419 "We want to inform you that a Nigerian prince wishes to send money to you" emails through!

It also acts as its own SMTP relay so that when you receive spam and phish emails--which you will, oh yes, believe me--you can't look at the headers to see where the emails came from.

We’re sorry to hear about your experience and understand how frustrating unsolicited email can be.

MailChannels is an email security company. We do not send email ourselves, nor do we permit spam on our network. When abuse does occur, the correct and effective way to address it is by reporting it directly through our abuse reporting process with full message headers so it can be investigated and stopped.

To ensure reports reach the right team and can be acted on, we provide clear instructions here:
https://www.mailchannels.com/report-abuse/

We take abuse reports seriously and act on them when they are submitted through the proper channels. Reports made without the required technical details unfortunately do not give us enough information to investigate or take action.

If you believe you are receiving unwanted email involving infrastructure we protect, we encourage you to submit a report using the process above so our abuse team can review it appropriately.

A trusted Canadian vendor!

We specifically required a Canadian data centre for our email handling and were delighted to connect with the sales team at MailChannels. We now have excellent analytics on the health of our SMTP sending from our website. Setting up our account was very easy and the periodic reports on our SMTP system health are very useful.

Hello MailChannels Support Team,

Hello MailChannels Support Team,

I recently tried to sign up for a MailChannels account and received the following message:

"We couldn't complete your signup because it was flagged as potentially fraudulent. Please contact support if you believe this is a mistake. [Error code: 100] [Case ID: 68fa225a05ec21.83205819]"

I believe this happened because I unintentionally created two accounts while trying to complete the registration.
I represent Mozserver, a legitimate hosting provider based in Mozambique, and we would like to use MailChannels to improve the deliverability and reputation of our clients' outgoing emails.

Our main domain: mozserver.co.mz

Please remove the block and allow us to proceed with one verified account.
We’re happy to confirm any details needed for verification.

Thank you very much for your understanding and assistance.

Best regards,
Gabriel Oliveira

Hi Gabriel, thank you for reaching out and for providing that context. We understand how frustrating it can be to hit a signup barrier when you're trying to get started.

This company is a spam

This company is a spam
Merchant. I get probably 20-50 emails a day from this joke of a company. I submit to unsubscribe and it bounces back as undeliverable on every single one. I forward to support and ask them to remove my email address and they just ignore it and say there’s nothing they can do. Anyone interested in filing a class action suit against this spam
Merchant

I have been contacted by mail channels with the same bs excuse as always. We have no control over what our customers send. The tell me there is no way to block my email address from there servers. I will just continue to send all bad reviews about this spamming company and forward all my spam emails to their support email until they decide it actually is possible to block my email address from their spam servers.

Anyone looking for an actual email serving company beware

Thank you for bringing this to our attention. We understand how frustrating unwanted emails can be, and we take spam complaints very seriously.

To clarify our role: MailChannels is an email delivery infrastructure provider, not the sender of the messages you're receiving. We provide email delivery services that legitimate businesses use to send their emails. Think of us like the postal service - we deliver mail, but we don't create the content or manage the mailing lists. That being said, we do take significant steps to detect and block spam and phishing from being sent via our platform and we have a very responsive abuse team that will take action based on your complaints.

Here's how we can help:

1. Report the specific senders: If you forward the unwanted emails to our abuse team as a .EML attachment (to abuse@mailchannels.com), we can identify which of our customers is sending them and take appropriate action, including suspension if they're violating our anti-spam policies. It's important that we be able to see the message headers, because this allows us to quickly pinpoint which of our customers the email came from.

2. Direct unsubscribe issues: The unsubscribe links in those emails are managed by the actual senders, not by us. If unsubscribe links aren't working, that's a serious violation we need to know about.

3. We enforce strict policies: We require all our customers to follow best practices for spam and phishing management and to be responsive when we report spam and phishing to them. We regularly terminate customers who are not playing by the rules.

4. We CAN block your email address: If you would like to ensure that email from MailChannels customers is never delivered to your email address, simply reach out and request that we add your recipient address to our global suppression list. Note that this will prevent you from receiving email from a wide variety of legitimate senders as well.

We'd genuinely like to help resolve this. Please send us the email headers of these messages so we can identify the problematic senders and take action. We're committed to maintaining a spam-free service and appreciate your patience as we work to address this issue.

This service blocks legitimate emails…

This service blocks legitimate emails constanly. Their spam filter is horrible. Do Not use this service unless you want the majority of your emails to be blocked. Horrible experience and they do absolutely nothing to help or fix it.

Dear La Jolla Quakers,

We’re sorry to hear about your experience. MailChannels is a service used by email hosting providers to help prevent spam and protect their networks. We don’t have direct control over individual mailboxes, but we work closely with hosting partners to investigate and resolve any issues that affect legitimate email delivery.

If you believe a message was blocked in error, please share the delivery details (including date/time, sender, and recipient) with us at support@mailchannels.com so we can investigate with your provider. We take false positives seriously and will do our best to ensure your messages are delivered as expected.

Reliable and Essential for Email Delivery

We've been using MailChannels since 2014, and it's been a game-changer for our email infrastructure. Their smart outbound filtering has significantly improved our deliverability rates and helped us maintain a solid sending reputation across all domains.
One of the biggest advantages is how MailChannels automatically identifies and quarantines compromised accounts before they can damage our IP reputation. This has saved us countless hours of manual monitoring and remediation.
Support has always been responsive and knowledgeable, even when we’ve had complex questions about SMTP integration or delivery logs. The dashboard is clear and easy to use, with real-time analytics that help us stay on top of everything.
If you're managing multi-tenant email or running shared hosting environments, MailChannels is practically essential. It just works — and that peace of mind is priceless.
Highly recommended.

Biggest pile of rubbish going

Biggest pile of rubbish going. Mailchannels simply eats outgoing and incoming mail on our web server,our host - Krystal - seems unable to communicate with Mailchannels effectively and admits that the false positive reports do not get back to them. Mail is filtered and binned totally - no chance to get it back unlike with other solutions - even if similar mail has gone through the filter on hundreds of previous occasions. Have had to reroute the majority of our business emails away from our own domains due to this complete junk.

***EDIT***

You've asked " If you can share specific message details".

This isn't going to really help. In the last month alone, you've blocked over 20 messages from UPS.COM, multiple from Paypal.com, a number from Royalmail.com and even some from HMRC that were genuine. I had to stop using eBay on addresses that pass through your lousy system ages ago because it was so unreliable and you even blocked multiple emails from Amazon. If you can't identify genuine emails from the largest companies and marketplaces in the world, your service is by definition junk. Search your own logs for UPS for example, you block so many of them it's a good place to start!

We’re sorry to hear about the trouble you’ve experienced. MailChannels provides spam filtering services to web hosting providers like Krystal Hosting, but we don’t manage individual mailboxes directly. When an email is flagged, our system follows the handling policy set by the hosting provider — including whether messages are quarantined or rejected.

We take false positives seriously and want to help. If you can share specific message details (date/time, sender, and recipient) with us at support@mailchannels.com, we can investigate with Krystal to determine what happened and work toward a resolution.

Just Terrible

Terrible. If they aren't missing genuine spam and letting it through, then they're flagging genuine email as spam. This is based on over 10 years experience with them. I'd change to a different service, but MailChannels is included with the hosting package and it would too time consuming to change all my domains over, plus I'd have to pay extra for each domain.

Avoid at all costs.

Mailchannels suspended a brand of us…

Mailchannels suspended a brand of us due to an international payment issue.
This has caused ALL of our Cpanel to not send emails

Biggest Problem is that their managers and billing team were not able to restore this in a reasonable time frame.

This has cause our whole webhosting brand to go down for hours.

DONT USE THEIR SERVICE IF YOU RUN CRITICAL MAIL SERVICES

Dear Michael Osterloh,

Thank you for taking the time to share your feedback. We take all customer concerns seriously and would like to address the issues you've raised.

While we understand your frustration with the service disruption, we'd like to clarify some important points. Your account was suspended only after falling significantly behind on payments. When we received your wire transfer, the payment couldn't be immediately reconciled because the company name on the wire didn't match your account information. This discrepancy, combined with the existing payment delinquency, led to the service interruption.

At MailChannels, we work hard to maintain reliable service for all our customers, which requires timely payments and clear payment information. To avoid future issues, we recommend:

1. Keeping your account current with payments
2. Ensuring wire transfers include proper account identification
3. Contacting our billing department proactively if payment issues arise
4. Giving us at least a full business week to receive, reconcile, and apply your wire payment to your account.

We value your business and understand the critical nature of email services. We'd be happy to discuss preventative measures for the future if you'd like to contact our customer service team directly.

Sincerely,
MailChannels

One of the worst services out there…

One of the worst services out there that unfortunately webhosts use and i hope every webhost transitions from this useless service to another.

Our email is only used to send out Order confirmations, Order Updates (tracking for shipments), abandoned cart (once per order after 48 hours) & review reminders (once per order).

Just because maybe a few probably 1-2 in our opinion as we do not run a large business maybe clicked spam on our email, they decided to block all outgoing emails today. So we couldn't update customers on their shipments, nothing!

Their response? "Uhh don't worry but we can't unblock this, you will have to wait for our auto system to unblock your email which is based on when spam reports get lower". No time frame nothing. What a joke of a company acting as god of emails.

I hope your company suffers a fast downfall!

MailChannels is the worst

MailChannels is the worst. They block legitimate WooCommerce email. I don't understand why hosting provider used it. When a new order is placed it send two emails, one to customer and one is for the shop. They block the shop emails. They say it is spam. Really, a WooCommerce email is spam. If someone accidentally marked is spam, don't let it go to that inbox only, what about the other customer?

I even setup Brevo for it. They still block the emails. Why?

I contacted the hosting provider and they said they can't do anything about it except asking us to buy email sending SMPT.

This is the second time I am facing it for my customer.

What a joke of a company

What a joke of a company. A Russian spammer used our form to submit some kind of spam iPhone link and our form is set to send a confirmation email back once we received your registration and mail channel decided to block ALL our outgoing emails for half a day on our most busiest day Monday. It took almost 12 hours to solve this issue and guess what? They can’t resend all the important emails our customers were supposed to receive but were blocked by them.

Hosting companies need to stop using this idiotic email company !

MailChannels was not trustworthy

MailChannels is not trustworthy. I started my service on 10/31/2023 and paid on the same date. I activated my account, added the SMTP to Postfix on my servers, and everything was working great. Up until I began receiving tickets from customers that their emails weren't sending - I'm very confused because MailChannels is known for their deliverability and that's why I'm paying the big bucks. So I check the console and lo and behold, my account is labeled "Status: Canceled". I received no warning, I have no spam as far as I know, and I've only ever managed to send less than 200 emails before this happened. My SMTP isn't working with them and I can't easily move back to my previous provider because I have to change Postfix and then update the SPF for all accounts manually on my end! I have no choice but to weather very upset customers who rely on email as the life-blood of their business. Customer's forms aren't working, their business emails aren't working, everything is dead in the water, and all because I wanted to provide my customers a higher level of service — I'd heard from everyone, after all, that MailChannels is the best. I learned my lesson. As of writing this, my services have ben interrupted for 2 and a half hours. Anyone in the hosting world knows that this is insane. I can provide receipts, anything necessary to prove my point.

Update:
MailChannels sales reached out to me and apologized, along with refunding my first month of fees. I felt the email was sincere and refunding the first month's fees is good customer service, so I'm updating my review to 3 stars.

Here's the email they sent me:
"[My name],

I deeply regret the disruption you experienced with our email services. It's clear that this sudden cancellation by our fraud detection system had significant implications for your business and clients, especially during such a critical moment in your meeting. The lack of notification regarding account cancellation and the potential loss of emails for the past three hours is genuinely concerning.

Email is, as you rightly pointed out, the life-blood of many businesses, including your customers. Unfortunately, the incident you described falls short of the standards we aim to maintain. I completely understand the gravity of this situation and the potential repercussions it has on your business's reputation.

We are already working on a thorough investigation of what led to this lapse, and I want you to know that we will take the necessary steps to prevent these occurrences in the future. As a goodwill gesture, we will refund your first month of fees.

Your feedback is invaluable, and I appreciate your patience as we work through this. We are committed to regaining your trust."

Thank you for taking the time to provide feedback on your experience with MailChannels. We sincerely apologize for the inconvenience you faced due to the sudden cancellation of your account by our automated fraud detection system.

Our intention behind not notifying users immediately about account cancellations is to prevent fraudulent actors from gaining insights into our system. However, we recognize the impact this had on your business and your clients.

I'm glad to hear that our team reached out promptly and addressed the issue. We genuinely value our relationship with our customers, and your feedback helps us improve and provide the best service possible.
