Creating an RSS Feed with an offset in WordPress

Mailchimp is a powerful platform for sending out html based email newsletters, and even includes the ability to create automated emails from your blog through the RSS feed, there is only one major flaw in the Mailchimp RSS based mailing system. Mailchimp lacks the ability to offset your RSS feed. Offsetting would allow for the ability for your most recent blog post to be featured and include an image, while also providing a list of other recent posts, but in a different format, such as with no image or no excerpt.

Offsetting can be a powerful tool for creating RSS driven html emails!

With a recent update to my subscription based notifications template, I wanted the ability to use post offsetting in my layout. Since Mailchimp lacked this functionality the solution was clearly to just make a new RSS feed that didn’t include the most recent post. While I expected this would present a challenge it turned out to be much easier than I expected.

To save others the trouble of figuring this process out, I have provided the required code to make it work below.

Creating an RSS Feed with an Offset of 1

Add the below code to your child theme’s Function.php file. Replace the words offset1 with what ever you want to name your feed file.

add_action( 'after_setup_theme', 'my_rss_template' );
 * Register custom RSS template.
function my_rss_template() {
	add_feed( 'offset1', 'my_custom_rss_render' );
 * Custom RSS template callback.
function my_custom_rss_render() {
	get_template_part( 'feed', 'offset1' );

Create a new feed template file and place it in your child theme’s directory. You need to name the file feed-offset1.php, where offset1 is what ever you want the file to be called. If you want your offset to be something other than 1, simply change the $more=1 to be any number you desire.

header('Content-Type: ' . feed_content_type('rss-http') . '; charset=' . get_option('blog_charset'), true);
$more = 1;
echo '';
do_action( 'rss_tag_pre', 'rss2' );
<rss version="2.0"
	xmlns:slash=""	>
	<atom:link href="" rel="self" type="application/rss+xml" />


Wondering. If I wanted multiple configurations, maybe an offset 1 and an offset 2, would I do this?

add_action( ‘after_setup_theme’, ‘my_rss_template’ );
* Register custom RSS templates.
function my_rss_template() {
add_feed( ‘offset1’, ‘my_custom_rss_render’ );
add_feed( ‘offset2’, ‘my_custom_rss_render’ );
* Custom RSS templates callback.
function my_custom_rss_render() {
get_template_part( ‘feed’, ‘offset1’ );
get_template_part( ‘feed’, ‘offset2’ );
