[00:00] In this video, I'll show you how to send  personalized emails to lots of people in Gmail   using a free add-on that I built. In just a few  simple steps, you'll learn how to send standard  

[00:13] mail merges, use custom subject lines, include  attachments, add CC and BCC recipients and more.   Best of all, it's 100% free. I'm Kevin and let's  dive in. First, head to Gmail. On the right-hand  

[00:28] side, open the side panel, and right over here,  click on the plus icon to browse add-ons. At the   top, search for Mail Merge by Kevin Stratvert.  That's my add-on. Right over here, click on   install. Here, sign into your Google account.  I'll click on continue. Then you'll need to grant  

[00:44] the required permissions. Right up on top, I'll  click on select all and then down at the bottom,   I'll click on continue. And just like that, we've  installed it. I'll click on done. And then over   here, let's close out of this window. You'll now  see a new mail merge icon over on the right-hand  

[00:57] sidebar. Let's click on that. This opens the mail  merge sidebar. Right up on top, let's click on   open mail merge. This opens up the main interface.  Let's start by creating an example spreadsheet.   I'll click here. This opens a new Google Sheet.  This spreadsheet contains all the personalized  

[01:13] information that you want to insert into your  emails. Let's walk through it together. First,   and this one is required, is the email column.  This contains the recipients of your mail merge.   You can enter one email address, or you could  even enter in multiple email addresses. If you  

[01:29] include multiple email addresses, you just have  to make sure to separate them with commas. All the   remaining columns that you see here are optional.  If you don't need them, you can delete them,   you can rename them, or you could even add more  here at the end. Let's enter in some sample data  

[01:44] to see how it works. Right over here, I'll enter  in an email address, a first name, a last name,   a company. And right over here, I could enter  in a CC or a BCC email address. I'll leave   those blank for now. Now, next to that is the  attachment column. To attach a file, all you have  

[02:01] to do is paste in a Google Drive file link. As an  example, here I am in Google Drive, and I want to   attach this PDF file to my mail merge. To do that,  I'll right click on this file, go down to share,   and right over here, you have the option to copy  the link. I'll click on that. Now, let's go back  

[02:17] to Google Sheets. Back within Google Sheets, let's  paste the link into the attachment cell. Right up   above, let's remove this sample data. Finally,  right over here, you'll see a custom column.   You could rename this to whatever you'd like. For example, I'll change this to due date and  

[02:33] then right down below, I'll enter in some sample  dates. You can add as many additional columns as   you need. With the spreadsheet ready now, let's  head back to mail merge. Now that we've prepared   the spreadsheet, let's select it in mail merge.  Over here, click on pick sheet from Drive. Here,  

[02:47] click on allow cookies. This opens the Google file  picker. Right here, I see my spreadsheet. I'll   click on it and then select. Next, let's compose  the email starting right here with a subject. I'll   type in invoice for, and then I want to insert  the company name. So right up here, I'll click  

[03:04] on the company merge field from the spreadsheet,  and that inserts it here as a placeholder. Notice   that each merge field corresponds to one of  the columns in the spreadsheet. Below that,   we can type in the email message. I'll  type in my message, and I'd like to say hi,  

[03:19] and then the person's first name. So, I need  to insert a merge field again. Right up on top,   I'll click on the first name, and that inserts  a tag. Here it says your invoice is due on,   and then I want to insert the due date. So up on  here, I'll click on due date. Now I'm not going to  

[03:34] use the last name merge field, and that's okay.  Now before sending, let's preview the emails by   clicking on preview. The first time you do this,  especially if you're including attachments,   you'll need to authorize access. So right  up on top, I'll click on authorize. Here,  

[03:48] let's click on allow cookies. And there I see my  attachment. I'll click on select. Here, you can   preview each personalized email exactly as your  recipients will see it. If you spot any issues,   simply click on back to edit, and you can make  changes. Now, I think everything looks good here,  

[04:03] so I'll click on send all. Up on top, let's  click on okay to confirm sending the emails.   And look at that, three emails sent, perfect. If  I open my inbox, there's one of the personalized   emails. Here, I have a custom subject. We also  have all the personalized details, the message,  

[04:20] and down below, we have the attachment, nice.  There you go. As you can see, sending personalized   emails in Gmail is quick and easy. The add-on  doesn't impose any sending limits, but Google does  

[04:32] have daily sending limits itself. As of filming,  you can send up to 500 mail merge emails per day   with a personal Gmail account, and up to 1,500  per day with a Google workspace account. If you  

[04:46] have any feedback or ideas for new features,  you could submit them directly in the app,   or you could simply leave a comment right down  below on this video. I'd love to hear from you.   I hope you find this add-on useful. Thanks for  watching, and I'll see you in the next video.
