Edit a Campaign

This page enables campaign authors to understand how to edit an email campaign in Mailchimp. It is part of the Build step in our Instructions for Email Campaigns.

Before you begin

If you haven’t already done so, log in to Mailchimp using the credentials our team provided, then find, open, and edit your campaign in the Campaigns section.

Edit a section

Select an area that you want to edit. A rectangle outline with Edit in the top right corner appears when hovering to indicate an editable area.

After a few seconds, the area on the right changes to display an editing area. Make your changes in this area, then select the dark gray Save & Close button at the bottom.

Omit a section


Hovering your pointer near the bottom edge of a section reveals an eyeball icon that enables you to omit the section directly above from delivery.

After clicking this eyeball icon, a gray, translucent overlay over a section indicates that it will not appear to recipients who receive the email campaign. You can confirm this by entering preview mode from the Preview and Test menu in the top right corner of the screen.

Omitting a section is useful in certain situations. For example, let’s say that you have built part of one section, but you later realize that you aren’t sure if it will be completed before you send your campaign. Omitting the section easily excludes it from the campaign before sending. Restoring it brings it back into the campaign before sending.

Thus you can easily control what sections your recipients will and won’t see, regardless of the build status of that section. The eyeball icon omits or includes the section. The gray overlay provides visual confirmation of an omitted section.

Add or remove a section



Hovering your pointer near the bottom edge of a section reveals a plus sign icon that adds a new section below. It’s not possible to add a new section above the very first section. To work around this, create a new section somewhere below the first section, then rearrange sections as needed.



Hovering your pointer near the bottom edge of a section reveals a minus sign icon that removes the section directly above.

Change a section type

Hovering your pointer near the bottom edge of a section reveals a picklist that enables you to change the type of section directly above. This is covered in greater detail in your training session.

Rearrange sections

Hovering your pointer below the top edge of a section reveals an icon with a two-headed arrow pointing up and down. Dragging this icon up or down enables you to move the section directly below to a new position in the order of sections.

Omit an element

Omitting an element works similarly to omitting a section except that it applies to a particular element instead of a section. Omitting elements enables you to create a wide variety of layouts throughout your entire email campaign. This is covered in greater detail in your training session.

Working with text

Pasting from Microsoft Word, Google Docs, or other sources often results in problems due to extraneous code. Instead of pasting directly from these sources, paste into the Online HTML Editor, click the Clean button in the top right corner, then copy from there and paste into Mailchimp. This results in clean code that will perform better across many devices and email applications.

Working with images

Your training session covers how to get the best results with images, particularly on high-resolution devices like smartphones and the latest displays. Here are some basic guidelines to remember:

  1. In general, image dimensions should be as large as possible. But no image should be larger in width than 1920 pixels. Wider than this and you are wasting users’ time, particularly those with slower connections.
  2. Each placeholder image specifies the ideal width followed by the manual setting of the width in Mailchimp. e.g., “1920w, set to 480” means that the ideal width of the image you upload is 1920 pixels, and in Mailchimp you should manually set the width of this image to 480 pixels wide (leaving the height field untouched).
  3. If an image filesize is larger than 350 KB, try to reduce its filesize without significantly reducing its quality before uploading to Mailchimp. Cropping non-essential portions of an image can help a lot.
  4. It’s not likely that you’ll get every image to meet the ideal dimensions or filesize. The closer you can meet these the better but don’t sweat it.
  5. Avoid inserting images outside of the placeholders which can result in images not displaying correctly across different devices.
  6. Set your alt tags unless the image is purely decorative.
