Connect Benchmark Email and Slack

Your Benchmark Email list changes every day: people join, leave, change their address or bounce. FlowMattic posts those changes to Slack so marketing can react to a bad send, sales can follow up on a promising sign-up and whoever owns the CRM knows when an email address changed. The workflows run on your own WordPress site.

When Benchmark Email fires Unsubscribe, FlowMattic runs Send Channel Message in Slack with the data from that event.

Benchmark Email and Slack workflows you can build

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.

Ready-made template

Post each unsubscribe to the marketing channel

A few unsubscribes are normal. A run of them right after a campaign tells the team to look at the subject, the frequency or the list that was sent to.

UnsubscribeSend Channel Message

View the template

Send business sign-ups to sales as a direct message

A Filter skips free email domains. A subscriber with a company address goes to the sales lead in a direct message, a warm contact who asked to hear from you.

Subscriber AddedFilterFind User by EmailSend Direct Message

Log cleaned addresses in a private list-health channel

When Benchmark cleans an address it will not be mailed again. The list owner sees each one and can check whether a customer's email needs updating elsewhere.

Email CleanedSend Private Channel Message

Tell the CRM owner when a subscriber changes email

Existing Email Changed posts the old and new address, so the person who keeps the CRM and the billing system in order can update the same contact there.

Route profile changes by the interest they picked

When a subscriber updates their preferences, a Router reads the interest field and posts to the channel of the product team that cares about it.

Ask the account manager to check on a customer who unsubscribed

A Lookup Table matches the subscriber's company to its account manager. That person gets a Slack reminder to check in before the customer drifts away.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

The profile trigger is named Profile Changed. with a full stop in FlowMattic. Pick it from the list rather than searching for the name without it.
If you run several lists, include the list name in every Slack post, so the team can tell someone leaving the newsletter from someone leaving a product list.
Each new subscriber runs the workflow once. Before a bulk import, switch the workflow off or add a Filter, so the channel does not get one post per imported contact.

Why run this pair with FlowMattic

Benchmark Email and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

A bad send is spotted on the day

Unsubscribes and cleaned addresses post as they come in, so a problem with a campaign shows up while you can still fix the next one.

Sales hears about warm sign-ups

Subscribers with company addresses go to a person who can follow up, instead of only joining an automated sequence.

List changes cost nothing per run

FlowMattic runs on your WordPress site with unlimited runs, so subscriber data passes through your server and a big list adds no fees.

Common questions

How do I get Benchmark Email unsubscribe alerts in Slack?

Create a FlowMattic workflow with the Benchmark Email Unsubscribe trigger and add Send Channel Message. Map the email and list name into the text, test with one unsubscribed address and switch it on.

What does Email Cleaned mean?

Benchmark Email cleans an address it should no longer send to, for example after repeated bounces. The Email Cleaned trigger lets you post those addresses so someone can check the contact in your other tools.

Will importing contacts flood Slack?

It can, because each added subscriber runs the workflow. Pause the workflow during a large import, or add a Filter that only passes sign-ups from your forms.

Can I see new subscribers with their details?

Yes. Subscriber Added passes the contact's fields, so you can post the name, email and list, or send only selected sign-ups to sales with a Filter.
