Should I use Gmail mail merge or a newsletter tool like Mailchimp?

Updated October 29, 2026

Short answer

Use mail merge for personal emails where you want replies: outreach, invites, client and parent updates. Use a newsletter tool like Mailchimp for designed newsletters to people who signed up, especially in the thousands. Mailchimp’s free plan covers 250 contacts and 500 sends a month. Gmail mail merge sends from your own address, up to Gmail’s daily limit.

Pick mail merge when

Pick a newsletter tool when

Many teams use both: a newsletter tool for the monthly update and Gmail mail merge for personal outreach. A Reddit thread about mass emailing from Workspace lands in the same place.

What about privacy?

With a newsletter tool, your list lives on its servers and each email carries its tracking. With a Gmail mail merge, the list can stay with you. Mergeline keeps lists, messages and results in your browser and adds no pixels. That matters if your list includes clients, students or donors who never agreed to a third party holding their details. Mailchimp, by contrast, notes that it uses a tracking pixel for opens.

Cost as you grow

Mailchimp’s price grows with your number of contacts. A Gmail mail merge costs the same whether your list has 50 or 500 people, as long as it fits Gmail’s daily limit.
