How to send email attachments safely without increasing the size of the email

Jose Argudo , CMO @ Mailrelay

We often want to add attachments to our bulk mailings or newsletters: PDFs with presentations or our service prices, videos, or even very large images. Although Mailrelay lets you attach files to your newsletters, we strongly recommend not doing so, for three reasons:

1. Anti-spam systems penalize bulk emails that include attachments.

2. You can fill up your recipients’ mailboxes or make your email load slowly. Keep in mind, in particular, that nowadays your email may well be opened on a mobile device.

3. You may use up your Mailrelay account credit unnecessarily, since one email is counted for every 100 KB of the email’s size.

When you need to send a file with your newsletter, it’s better to upload it to a web space and then add a download link to the body of the message. All you need to do is upload it to the www directory on your website’s FTP. For example, if you want to attach dossier.pdf, connect to your FTP with your connection details using Filezilla or another FTP client, and once the file is uploaded you can link to this URL:

http://midominio.com/dossier.pdf

Replace midominio.com with your website and dossier.pdf with the name of your file.

If you don’t have access to your website’s FTP, you can use an online storage service such as Dropbox or Google Drive.

A. To upload the file you want to attach to Dropbox

Create an account at www.dropbox.com and log in to access your online space. Click the “Public” folder, click “Upload” at the top, select the file on your computer and then confirm:

Once the file has been uploaded, right-click it and select “Copy public link”. You now have a link to the file that you can insert in your email, so recipients can download it from your Dropbox without it being attached.

B. To upload the file you want to attach to Google Drive

Create a Google account. If you have a Gmail account, that will do. Log in and go to https://drive.google.com. Click the “Upload” button on the left, right next to the “Create” button. Select the file on your computer and then confirm. You’ll see it uploaded:

Google Drive “Create” menu with the option to upload files

Right-click the file and select “Share”:

Where it says Private, click “Change”. Select the first option, Public on the web, and click Save:

Google Drive sharing visibility options with “Public on the web” selected

You can now copy the URL shown in the sharing link field.

Remember to send yourself a test before sending the newsletter with the attachment, to check that the link works, and don’t forget to log out of the system you use first, whether it’s Dropbox or Google Drive, since that’s how your subscribers will see it.

Now you can send your bulk mailings without increasing your costs.

Do you use other platforms to share files?
