Who is XLTools Mail Merge for

Say, your company plans to hold an event and you need to send out email invitations to some 50-60 partners. To avoid spammy look, you want each partner to receive a personalized email addressing them by name.

XLTools Mail Merge helps you do exactly that, saving your hours of work.

Note, that XLTools Mail Merge is not a email service provider – it's an Excel productivity add-in. While XLTools does not set a sending limit, your email provider most certainly does, as well as violation penalties.


How does mail merge in Excel work

XLTools Mail Merge add-in is NOT an email service provider. It is an Excel productivity add-in that simplifies sending bulk personalized emails – with very little setup time:

  1. Connect Mail Merge to your email account.
  2. Create a list of recipients in an Excel table.
  3. Create an email template, add placeholders for personalized data.
  4. Click 'Send' – and send out bulk personalized emails without leaving Excel interface!

The Mail Merge add-in cannot in any way effect spam filters of any email. Ultimately, you сannot predict whether your recipient's mailbox labels (or not) your email as spam. Each email provider has its own spam filtering algorithms.


How to connect Mail Merge in Excel to your email account

Connect Mail Merge in Excel to your email account via SMTP (Simple Mail Transfer Protocol for email transmission). It works for almost any email account: private or corporate Outlook, Gmail, Hotmail, Yahoo, ISPs, web hosting providers, SMTP relay services, etc.

  1. Click the 'Settings' button on the XLTools tab > Open 'Mail Merge (SMTP)' tab.
  2. 'Sender email' – your email address, which will be used for sending bulk emails.
  3. 'SMPT Server' and 'Port' populate automatically; otherwise contact your system administrator.
  4. 'From Name' – your name, or company name, or any other name as you want it to display in recipients' mailboxes.
    E.g. "XYZ Seminars".
  5. 'User Name' and 'Password' – connect to your email account.
  6. Check the box 'Use SSL/TLS' if necessary. Cryptographic protocols SSL (Secure Sockets Layer) and TLS (Transport Layer Security) create a secure link between your email server and your computer.

To test the connection with this email account, click the "Send Test Email…" button. A test message will be sent immediately.

How to create a list of recipients in Excel

Excel table is a convenient way to store your contacts. Each row of the table stands for one recipient. Each column represents a personalized field, such as Email, Title, First Name, etc. This Excel table serves as a data source for the Mail Merge add-in. Data in these personalized fields will later replace the respective placeholders in your generic email template.

To create a list of recipients from scratch:

  1. Click the 'Create Mailing List' button on XLTools tab.
  2. Check boxes for columns you want to create, e.g. First Name, Last Name.
    Note: 'Email' column is included by default.
  3. Check 'Attachment' boxes, if you want to attach files.
  4. Choose whether to place the mailing list on a new or an existing worksheet.
  5. Click 'Create' > Done.
  6. Fill the table with your data. If necessary, manually add more columns for other personalized fields, e.g. RegID. The number of columns is not limited.

  1. Open your contact list in Excel.
  2. Format the list as a table:
    Select the range > Click 'Format as a Table' on the 'Home' tab > Apply any suitable table style.

How to attach files to messages in bulk email

You can send 1 or 2 files to each recipient of your bulk email. You can attach any file format: PDF, DOCX, PPTX, XLSX, JPEG, etc. Consider the attachment size limitations set by your email provider. Normally, the size of messages with attachments cannot exceed 10-20 MB.

  1. Open your recipients list.
  2. Add a column to hold attachments:
    • To send one file: add one column, e.g. 'Attachment 1'.
    • To send two files: add two columns, e.g. 'Attachment 1' and 'Attachment 2'.
  3. Specify the file path on your computer, e.g. C:\Documents\Seminar-Agenda.pdf.
    • To send one and the same file to all recipients: copy the file path into all cells in the attachments column.
    • To send different files to different recipients: specify file paths for each recipient individually.
    • To send no attachments to some recipients: leave the respective cells blank. 

The specified files will be attached to messages in your bulk email. Next, proceed to creating an email template.


How to create a template message and send personalized emails

Email template is a generic impersonal email message. Utilization of placeholders in a template allows you to automatically personalize each message: the Mail Merge add-in will pull data from your Excel contact list and replace these placeholders with specific data for each recipient. E.g. it will replace a generic placeholder [Name] with the actual name of the recipient "John".

  1. Click the 'Send Emails' button on XLTools tab > A dialogue box will appear.
  2. Specify the range of your mailing list including headers.
  3. Verify the column, which contains recipients' email addresses:
    E.g. select the 'Email' field.
  4. Verify columns, which contain paths to attachment files:
    E.g. select the 'Attachment 1' and 'Attachment 2' fields.
  5. Type the 'Email Subject' as you want it to display in recipients’ mailboxes:
    E.g. type 'Seminar Participation Confirmation'.
  6. Enter your message in the editor:
    • Type a message. If necessary, you can use a set of text formatting tools: font, color, alignment, insert link, insert image, etc.
    • Or, click the 'Load HTML from File' button, if you want to use your existing HTML template.
  7. Choose from available placeholders and insert them in square brackets:
    E.g. [First Name], [RegID].

Create email template for bulk emails with XLTools Mail Merge


Please note: after you click 'Send' and until all emails are sent, it is impossible to make changes to your recipients list or your email template. We recommend testing your template first. E.g. create an test list of recipients which includes only your own email addresses – and send the email to yourself. Check that all placeholders are replaced with personalized data properly, check for errors or typos in the email subject and message. Make sure your email has a professional look.

Once you click 'Send', XLTools Mail Merge will immediately start sending bulk personalized emails:

  • Messages are sent one after another, directly from Excel interface.
  • Email status (either 'Sent', or an error indication) will appear in the last column of your mailing list.
  • Find sent messages in your 'Outgoing' or 'Sent' emails.
  • Note: email delivery status is not tracked.

  • Specified files are automatically attached to the email.

What is the sending limit of XLTools Mail Merge

XLTools Mail Merge is not a email service provider and does not limit the number of sent email messages. Bulk emails are sent from your email account.

Please note: each email provider has own policies on outgoing email quotas, attachment size and mailbox size. Exceeding the sending limit may lead to lockdown, blacklisting, additional costs or other penalties. Please contact your email provider to find out your SMTP email sending limit.

  • Free email accounts are intended for private communications and are not built for mass emails. E.g., Gmail and Hotmail have about 50-100 messages/day limit.
  • Corporate email or your own SMTP-servers permit much higher number of outgoing email.
  • Specialized mass email services, e.g. SendGrid or MailChimp, offer thousands messages per month depending on a subscription plan.

    Can we send email from generic email id to diffrent vendors??

    • Maria Balobanova says:

      Hi Nagashree,
      Yes, you can, if by generic email you mean an email address that can be used by multiple members (for example: info@, support@, etc.). You can connect to this generic email account using the Mail Merge feature via SMTP. Once you connect, send the emails to your vendors. Keep in mind not to exceed the limitation of your account on the number of outgoing bulk email.

  2. Kumaran Ramadass says:


    When I try to send mail, I get a message saying I’m about to send 0 mail.

    I have added the email address in email column but still get such error message.

    Kindly advice.

    • Maria Balobanova says:

      Hi Kumaran, we’ll need to see the screenshots and your mailing settings to find out what causes the error. I have sent you an email.

  3. Kit says:

    May i know your software can support add different password to the attachment?

    • Maria Balobanova says:

      Hello Kit,

      You can send different attachment to different emails – just specify the path the the files. If you attach a password protected document, the recipient of the email will need to know the password to open the file. But you cannot set or change passwords to the attachments with Mail Merge – you have to set protection to the files separately.

  4. Chris says:

    Is it possible to have a one-to-many mail merge e.g. to send values from multiple rows in one mail if the email address is the same. I ma looking to send data for multiple employees to one manager so if:

    employee 1 data1 data2
    employee2 data1 data2
    employee3 data1 data2

    manager1 gets a one mail with data for 2 employees
    manager2 gets 1 mail for 1 employee

    is this possible?

  5. Peter Liapin says:

    Hello Claudio,

    Sorry for the delay with the answer. Yes, it will be possible in the new version of XLTools which we are going to release really soon.

  6. Claudio says:

    Good afternoon and congratulations for the free application that works perfectly.
    I would be interested in the mail merge and I wonder if it is possible to insert an attachment to the email.
    Thanks and regards
