Mail merge with Outlook, without Word
Outlook's own mail merge runs through Word. Here you connect the mailbox you use in Outlook (Microsoft 365 or your own domain), upload the Excel and send everyone their own email from your address, straight from the browser.
Upload Excel and startFree up to 50 emails a day. No card.
How it works
- 1
Upload your Excel or CSV
- 2
Write one email with {{Name}} and other columns
- 3
Send it from your own mailbox
Works with Gmail, Microsoft 365 and any mailbox on your own domain.
Which mailboxes connect
A company Microsoft 365 mailbox connects with its address and password once its administrator allows authenticated SMTP for it; if the login is refused, DataSend tells you exactly what to switch on. A mailbox on your own domain that you read in Outlook connects the same way. Personal @outlook.com and @hotmail.com addresses can't be connected: Microsoft no longer lets other apps send from them with a password.
Reminders Outlook doesn't do
Outlook sends a mail merge once. DataSend also reminds everyone who hasn't replied, after the days you choose and in the same thread, and skips those who did.
Questions
Is it free?
Yes, up to 50 emails a day and 500 recipients in one mail merge. On the free plan each email ends with a small "Sent with DataSend" line. Paid plans have no daily cap beyond your mailbox's own limit and no line.
Will my emails end up in spam?
They go out from your own mailbox, one by one, spread over the day, each addressed to one person, so they look like the emails you write by hand. Addresses that don't exist are found and skipped before sending, so your mailbox doesn't collect bounces. Each email also carries the one-click unsubscribe header Gmail and Outlook expect.
What file can I use?
Excel (.xlsx, .xls), OpenDocument (.ods) or CSV. The first row holds the column names; one column needs the email addresses. Every other column becomes a field you can put into the text. The file is read in your browser and nothing is uploaded until you send.
Can recipients see each other?
No. Every person gets a separate email with only their own address in it, unlike a BCC blast.
