The apology email: do's and don'ts

I am doing

• Be honest

This may seem obvious, but many companies still forget about honesty by resending correction emails. If you can get customers to apologize sincerely, it can make up for your mistake and give customers a good impression of your company. Phrases like "We realize we made an unacceptable mistake" or "We're very sorry" will make your apology more sincere.

• Be in good weather

The sooner you send your letter of apology, the easier it will be to correct your mistakes. If you send a botched email and don't send another apology until next week or month, it will show customers that you are lax in customer service and cause them to lose confidence in your brand.

One tip for sending an apology email on time is to check it outbefore and after shipmentand send correct emails as soon as you realize you're wrong.

• Don't forget to add a valid attachment to your apology email!

You might think, "I'm not stupid enough to make two mistakes with attachments sent to customers within one day!” but trust me, you may forget it sooner than you think.

If you send your customers an apology letter for a mistake and do not attach the relevant document to your email, your email will be a huge waste of time for your customers. As a result, this may give your business a bad impression or worse, may move your address to the spam folder if he finds you annoying.

You don't have to

• Don't make excuses

You may think that reporting bugs and giving legitimate reasons for bugs is a good way to gain customer sympathy, thus protecting your brand image. However, in reality it is usually the other way around. Using "sorry" in an apology letter for mistakes can make customers believe that you're not sincerely apologizing, which will leave customers with a much worse impression of your company.

Instead of explaining the reasons for your mistakes to your customers, it's better to use phrases like "We know there's no excuse for this" or "We realize it's our fault" to atone for your mistakes.

• Don't blame anyone else

Some companies usually try to shift the blame to someone else, such as their employees, employees, or even customers, to avoid making their mistakes look bad. However, this can make you and your brand look worse in the eyes of customers.

All customers care about is thisyou made a mistake that worries themnot who is at fault, and absolutely not if they are the cause of the error. A sincere email apologizing for a mistake always makes customers feel better than an unnecessarily long explanation of who is at fault.

• Don't turn an apology email into an advertising or sales email

Offering product coupons or discount codes to customers in an apology letter is an effective way to fix mistakes. However, rememberDraw a lineso as not to become a sales email.

Some companies offer discount codes to customers in apology emails and require customers to complete a survey or answer certain questions to receive the codes, which will annoy customers rather than make up for the inconvenience caused.
