We knew people would have questions, so we’ve compiled the most frequently asked questions and shared them here. We’ll also update these and share them on our Knowledge Base in the future.

The most frequently asked questions we get for Proxy Mailer

Does Proxy Mailer cost extra?

No, Proxy Mailer is a tool that’s included with any of our existing plans. Just make sure you have a plan that supports the number of “tool runs” you expect to use. For example, if you plan to use this tool to send 20,000 emails a month, you’ll want to be on a Standard plan (up to 50,000 tool runs) or higher. You can see the different pricing thresholds here.

Does this work for all Keap plans?

We highly recommend you use this tool only if you are on Keap Max Classic. Keap Max Classic has the ability for you to adjust your email engagement settings so they don’t get marked as “Unengaged Unmarketable” while using Proxy Mailer.

If you are on another version of Keap, after 4 months your contact’s primary email addresses will be marked as “Unengaged Unmarketable”, and you will lose the ability to communicate with those contacts permanently.

We show you how to adjust these settings with Keap Max Classic in the tool setup inside PlusThis.

Who would benefit most from this tool?

This tool is a scalpel, not a net. So the ideal user will be someone who has confirmed contacts that are bouncing or not getting your emails through Keap.

Sometimes this can happen if you’re in an industry like finance, that can have trouble getting through. Or if you have transactional emails that are getting blocked for being marketing.

Using your own private IP will allow you to send emails using your own private email deliverability reputation. That may help you in some situations but is not a guaranteed silver bullet.

The best practices for email deliverability will apply even more so if you are going to use Proxy Mailer. Since you are emailing on your own reputation, bad practices will sink your deliverability even faster than if you were doing the same bad habits but on a shared IP. 

Would I need another service to make this work?

PlusThis is serving as a proxy to create a virtual email to be used by your private IP. The easiest way to get a private IP to send emails through will be Mailgun. We highly recommend going this route. Mailgun has a Foundation 100k plan for $85/mo that can send up to 100,000 emails a month, AND provides a dedicated private IP address. The $35/mo plan uses Mailgun’s shared email servers and is not something we recommend as it is the same as Keap’s setup.

If you’re technical and understand how to set up your own private SMTP server, you can use this as an option as well. There are a few gotcha’s and caveats to using SMTP because it lacks the API and Webhooks that Mailgun is able to offer.

Since this is a more technical tool, most of the people using this tool will likely have IT and dev resources who are savvy enough to implement a service like this and understand the reasons behind why it could benefit them.

Hey, does Keap know you are doing this?

Yes, we’re actually in touch with Rich Sharpe, the PM over Email Deliverability, and his team making sure we iron out any compliance issues and monitoring how the tool is impacting users on both sides.

PlusThis wants to provide tools that help Keap users and this in no way is meant to compete with the shared ips Keap uses to send emails. Having an option to send from your own private IP will be another tool in Keap’s arsenal to help people who may be in a specific situation where it makes sense to use this. We’d rather they have this option available, than call it quits with Keap and find their deliverability still haunting them on the next CRM they try.

PlusThis has been getting great deliverability using Keap and will continue staying on a shared email server for the foreseeable future.

What kind of email capacity and speed can I expect?

PlusThis has a unique system of queues and lightning fast response times. What this means is that we can receive hundreds of thousands of requests and respond immediately.

When we receive a Proxy Mailer email, we actually send the data to a queue to be processed. When the email comes up in the queue, we perform a couple API requests to load contact information, repackage the email for transport, and send it off. This entire process can take anywhere from a couple of seconds to a couple of minutes depending on multiple factors: the current queue size, your PlusThis account status, throttling issues, and server/api response times. 

How do unsubscribes work?

Following our setup guide will help you greatly here.

By default, your campaign emails will likely have an “Unsubscribe” link or button that takes the contact to Keap’s opt-out form, and the contact’s email address is opted out.

We do not modify any of the email content, so unsubscribe links are fully preserved and the contact will still be able to opt-out. However, when you are using the Proxy Mailer tool, the contact’s Virtual Email Address is where Keap is sending the email to, and it is the Virtual Email Address that is opting out, not the primary email address.

To solve this issue, as part of the tool setup, we show you how to create an automated task inside Keap to notify the Proxy Mailer tool whenever a contact’s Virtual Email Address opts out and unsubscribes. When we receive the notification, we will opt-out the primary address as well.

Will my links and other Keap automation tools work if I use Proxy Mailer?

Yes, we pass the headings and data from Keap so all your links and automation work as expected. No additional work required.

Who can I talk to about email deliverability if I suspect we’re having problems there and what I should do as next steps?

We personally consult with Evan and Adrian over at Email Smart when it comes to any email deliverability situations.

If you’re running email marketing but haven’t worked with a professional on your deliverability plan, I highly recommend their team. They can also recommend the right tools for monitoring, maintaining and improving your email deliverability.

Proxy Mailer: Help Get Your Emails Delivered

Update: While we’ve gotten some great feedback on the tool, unfortunately, it has been canceled indefinitely due to Keap rules that prevent us from successfully providing the tool.


Marketing CRMs like Keap are miracle makers. It’s a wonder that we can send our message to so many people, in so many places, at the exact time we want.

However, if you’ve been doing email marketing for any amount of time, you’ll quickly discover not all emails make it to your customer’s inbox.

Sometimes this is due to bad actors that buy lists, spam, ignore email engagement, and disregard other best practices. But even the best actors can struggle to get important emails delivered.

That’s why we are launching our newest tool Proxy Mailer.

Your Emails Are Affected By The Email Reputation Of Others…But It Doesn’t Have to Be That Way

By default, Keap sends your emails from a specific IP address (or server) that is shared with other Keap users. This isn’t necessarily a problem if all of Keap’s users are following good email practices.

Let’s say, however, I’ve bought a list. I send emails to list contacts even though they never opted in. In addition, I keep continuing to email the same people over and over again regardless of whether or not they are opening or clicking links in my emails. It won’t take long for Google, Apple, Yahoo, and other email providers to say “Bryce is a bad emailer, let’s put his emails in junk/spam/promotions”. They will likely notify Keap of my behavior, but sometimes they don’t. If I don’t stop my behavior, those email providers may not only block my emails, but also emails from any other Keap user using the same IP address/email server. My bad actions could cause other Keap users massive deliverability issues. Don’t be like me!!!

If there is a bad actor on your email server, you could be following the best deliverability practices and still have trouble getting emails delivered in the inbox. Previously valid and verified email addresses may even start bouncing all your emails. These bad actors are screwing up your deliverability!!!

That’s where an email proxy service like ours might help.

What is Proxy Mailer and How Does It Help Get My Emails Delivered?

Proxy Mailer allows you to send your emails via private SMTP. So, instead of being lumped in with the email reputation of other Keap users, you will be sending from your own private SMTP where your email reputation is completely controlled by your email behavior.

This can be very helpful for people who may be in an industry like finance, where emails typically have trouble with deliverability. Or in cases where you have transactional emails that are having trouble getting through.

How It Works

There are four parts to sending emails through a proxy.

  1. Onboarding: Using Proxy Mailer, we’ll set up a Virtual Email Address for all of your contacts.
  2. Emails: Going forward, when you send an email it will use the contact’s new Virtual Email Address. The people you are sending emails to will still see emails coming from your normal name and email address, it will just be coming from your private SMTP instead of the shared SMTP that Keap sends through.
  3. Emails Received: When you send an email it gets picked up by PlusThis and run through the Proxy Mailer tool.
  4. Forwarding: Your email then gets re-sent through your SMTP provider (we highly recommend Mailgun). Everything works just like before. When your contacts get their email, any link clicks get tracked, tags applied, and unsubscribes registered.

5 Examples of How You Can Use Slack Notifications to Make Your Life Easier

If Slack is an integral part of your daily life, at some point, you may have wished you could receive Slack notifications for all the important things happening, or that you need to remember. 

Something like:

Slackbot: Hey – stop working for 2 seconds and eat lunch!

or…


Slackbot: Yo – don’t be late AGAIN. It’s time to pick your kid up from school!

or…

Slackbot: Sound the alarms! You have a new lead….go!

While we can’t help you get notifications for all of your personal reminders, we can inform you of important things happening in your business. We recently launched a new Slack Connection tool where you can receive Slack notifications in a channel of your choice with custom messages that you configure.

The possibilities are endless of how you can use this tool in your business.  From sales lead notifications, to informing you when a contract or important document is signed, to even letting you know when someone responds to your text messages…this tool can be set up so you won’t miss a beat.

We’re going to cover a few examples of how you can use this amazing new tool in your business.

1. New Lead Notifications – Time is of the essence when it comes to reaching out to new prospects. You probably know the dreaded feeling when you miss out on a potential lead all because you didn’t see the email or notification in your CRM on time. No fun, right? Using the Slack Notifications tool, you can set up a notification to be sent whenever you have a new lead. Don’t forget to include the lead’s contact information, so you can grab the lead’s info directly from the notification. 

2. Signed Documents – There’s no better feeling than a signed contract from a new client. Get notified immediately when your clients, prospects, or customers sign an important document, so you can know exactly when things are happening in your business.

3. Text Message Response – Communicating with clients, customers, and prospects via text is becoming increasingly more popular. Set up a Slack notification to be informed whenever you receive a text message response back! This can help speed up the workflow when you’re relying on specific information from clients that can’t be automated.

4. Client Onboarding – Sometimes there are tasks that need to be handled manually as part of the onboarding process. With Slack notifications, you can be notified whenever your clients have completed the steps needed prior to your team manually onboarding. Whether it’s reaching out to them with a welcome call, or a quick text message, Slack will notify you when it’s your team’s turn to step in.

5. Payments Received – Cha-ching! Get notified when your customers place an order, or your clients pay their invoices. Or, receive notifications with missed payments, so you know when to reach out to personally to your clients.

Now that you have a few examples of how you can use Slack Notifications in your business, head here to see how to set it up. Then, sit back, relax, and enjoy all the notifications heading your way!
