The Art of the Custom Field: Fewer Questions, More Supporters

"I'm Sarah and I just finished the Denver 10K in 52:34." The only two things she typed were her name and her time. The rest of the sentence was already waiting for her in the campaign's caption template, written as "I'm [Your Name] and I just finished the Denver 10K in [Your Time]."

Two blanks, about fifteen seconds of typing. 

Now picture the same campaign asking for five: name, time, bib number, hometown, and the training group she runs with. Same race, same design, same pride. Most people would close the box.

Every blank is a question, and questions cost you

A custom field is a blank space in the caption that supporters fill with their own details. It is one of the simplest ways to personalize a Twibbonize Campaign, and one of the easiest features to overuse.

A supporter came to say something about themselves, not to fill out a form.

They have already chosen your campaign. They may have uploaded a photo, edited their design, and reached the point where they are ready to share. Every field you add puts another small decision between that moment and the final post.

A filled-in blank works best when it turns a general statement into something that feels like it belongs to the supporter.

“Proud to be part of the Class of 2026” feels different from simply saying “Proud of our graduating class.”

The first gives the supporter something specific to say about themselves. That is the reason the blank is there. The real question is what the field is for.

A field that makes the supporter’s message more personal belongs in the campaign caption. A field that mainly collects information for the organizer probably belongs somewhere else, if it needs to be collected at all.

Keep the one detail they would actually want to share

The custom fields that earn their place usually carry some kind of identity, pride, or achievement:

• A finish time.

• A graduating class.

• A jersey number.

• A hometown, when hometown is part of the identity.

• A team.

• The year someone joined.

The ones that usually do not earn their place are details supporters have to look up, information you mainly want for your own records, or anything that makes someone stop what they are doing just to figure out the answer.

If they need to open another tab, check an email, or search for a number before they can finish the caption, ask whether the field really needs to be there.

And if you are certain that one field is not enough, keep the second one short. The goal is not to force every Twibbonize Campaign to use exactly one custom field. It is to make every field justify the extra effort it asks from the supporter.

How to use Custom Fields in your campaign caption

Twibbonize lets you place a Custom Field directly inside your Campaign Caption, so supporters can personalize part of the message before sharing. Start by writing the caption as a complete sentence first. Then look for the part that would become more meaningful if the supporter could make it their own.

For example:

I’m [Your Name], and I’m proud to support World Cleanup Day 2026.

Or:

Proud to represent the Class of [Graduation Year].

Or:

I finished the 10K in [Finish Time].

The important part is that the custom field fits naturally into the sentence. It should feel like part of the caption, not a questionnaire attached to it.

When setting up your Twibbonize Campaign, place your cursor where you want the personalized answer to appear in the Caption Template, then use Add a Custom Field to your Campaign Caption and give the field a clear prompt such as “Your Name,” “Graduation Year,” or “Finish Time.” Keep that prompt simple enough that supporters immediately know what to type.

Twibbonize recommends keeping Custom Fields quick to fill in; one or two short fields will often be enough to personalize the caption without making the experience feel heavy.

A few things are worth checking before you publish:

• Write the sentence first, then add the field. Do not start by deciding what information you want to collect.

• Make the prompt obvious. “Your Name” is easier to understand than something vague like “Personal Information.”

• Ask for something supporters already know. Avoid details that require checking another source.

• Read the finished caption with a real answer inside it. Make sure it still sounds like something a person would naturally post.

• Keep it short. If the caption needs several fields to make sense, simplify the caption before adding more.

A Custom Field should make a caption feel more personal without making it harder to share.
