Outlook Mail Merge email limits

Though very useful, Outlook mail merge has several limitations:

• No analytics, tracking, or way to see which recipients have opened, clicked or replied
• It's only compatible for Outlook email address and can't be used with Gmail accounts
• It's limited to individual use, meaning the results can't be shared with other teammates, and therefore it's not collaborative
• The UX is outdated and clunky
• You must toggle between three different applications (Microsoft Word, Excel, and Outlook) to send merged emails
• You’ll need to opt-in for an Office 365 subscription (which starts at $12.50/user per month for business use) or use proprietary versions of the software ($249.99 for one computer) to use Outlook mail merge

Why use mail merge in Outlook?

Personalization is key when it comes to email marketing. By using mail merge tools and variables such as [firstname], [lastname], [companyname], and [jobtitle], we can create customized and targeted messages that make the recipient feel special and valued.

When an email feels personalized, it's more likely to catch the reader's attention and encourage them to engage with the content. This can lead to higher open rates, click-through rates, and ultimately, more conversions.

If you want to take your email marketing to the next level, consider using mail merge tools and personalization variables to create more effective and engaging campaigns.
