Q&A Highlights

What’s the first step when an email mistake happens?Acknowledge the problem immediately. Ignoring or delaying a response typically worsens subscriber frustration and increases reputational damage.
How do you stop an issue from escalating?Act fast: pause the send, halt the campaign, or escalate internally depending on severity. Major incidents like data breaches require immediate involvement from security and IT teams.
What should marketers assess after the immediate issue is contained?Determine impact: how many subscribers were affected, what went wrong, whether sensitive data was exposed, and whether legal or security teams must be involved.
Why is having a crisis communication plan important?A plan provides clear internal steps, establishes responsibilities, and ensures consistency in how subscribers are informed and guided through next actions.
What must an apology email include?A clear subject line, branded template, straightforward explanation, actionable guidance for subscribers (e.g., password resets), and a sincere apology.
What should marketers avoid in an apology email?Humor, vague language, burying the lede, evasive wording, sending from no-reply addresses, or messaging subscribers who weren’t impacted.
Why is a branded template recommended for apology emails?Consistency reassures subscribers that the communication is legitimate and reduces the chance they’ll mark the message as spam or phishing.
When should an apology not be sent?If the original error involved emailing an old suppression list. Sending again could compound the issue and trigger further spam complaints.
What should teams monitor after resolving the incident?Deliverability signals: inbox placement, reputation metrics, bounce patterns, and spam complaints. Incidents can temporarily affect future sends.
When do legal considerations apply?Incidents involving security breaches, exposed personal data, or regulatory implications require legal oversight — and in many regions, notifying affected users is legally mandated.

Let’s face it. We all make mistakes.

Add the crush of the approaching holiday season, and it becomes even more likely that email marketers somewhere (maybe even you!) are panicking about a misfired campaign, an email that starts with a cold "Dear <FirstName>," or even a data breach. The list goes on and on.

When a mistake happens—and yes, it’s a matter of when, not if—it’s important to have a plan in place to limit the damage and start to make things right. Here are six recommendations for how to handle these difficult situations in a manner that’s sensitive to your subscribers and to your brand.

1. Own the problem.

Acknowledging the problem and taking responsibility is the first crucial step in addressing a crisis. Trying to ignore the situation and hoping no one notices will only make it worse.

2. Put out the fire.

It’s critical to put a stop to any active issues. How high to escalate the issue, and the steps required for resolution, will depend on the type of problem. If it’s a true crisis like a data breach, your company’s security and IT teams need to get involved (and take charge) immediately. On the other hand, if dealing with something more minor like an incorrect subject line or campaign sent to the wrong segment, a simpler response like halting the campaign may be appropriate.

3. Assess the business damage.

Once active harm has stopped, evaluate the mistake’s impact. Consider: How many subscribers were affected? Which segments? Was personally identifiable information released? What caused the issue? Will it result in costs? Do you need to involve legal or law enforcement? Some questions are appropriate for marketers, while others require your company’s security and legal teams.

4. Create a plan.

With the guidance of appropriate stakeholders in the company, lay out clear steps for telling subscribers what they need to know and for making the situation right. Your plan should address both internal steps and what subscribers need to learn. Consider whether subscribers must take action, if compensation is warranted, or if business process changes are necessary. Identify key people responsible for implementing fixes.

5. Inform your customers and apologize.

When preparing your response email, consider these elements:

DO:

Use a clear subject line (e.g. "We made a mistake." or "Notification of Data Breach")
Use a branded template for consistency so subscribers recognize it and are less likely to mark it as spam
Include any steps subscribers should take to protect themselves, such as changing passwords or enabling two-factor authentication
Be clear and direct. Describe the situation clearly and as succinctly as possible. Don’t bury the lede, obfuscate, or use weasel words.
Apologize. Whether the error was big or small, expressing regret is an important part of resolving the problem
Consider that you may need to address customer feedback in response to the email, so don’t use a "no-reply" address

DON’T:

Try to be funny. Stay straightforward and honest—making light of mistakes doesn’t resonate well with subscribers
Send the email to subscribers who weren’t affected. The last thing you want is to make another mistake by sending it to too many people! If you sent a campaign to an old suppression file, avoid sending an apology email, as this could compound the problem.

6. Proceed carefully.

After the immediate crisis has been resolved, it’s appropriate to take stock of its impact on your ongoing and future email marketing, including assessing damage to your technical sending reputation. Work with your deliverability team to monitor performance and proceed with caution, understanding that you may see negative results on the next send.
