70+ Fundraising Email Subject Lines to Boost Donations in 2026

Why the subject line matters in a nonprofit email

When it comes to email marketing for nonprofits, the subject line predetermines the email experience. It’s the first text a subscriber or recipient sees — and the decision point on whether or not to open the email. 

A well-thought-out subject line intrigues the reader and encourages them to open the email, increasing engagement and donations for your fundraising efforts. In contrast, a bad and bland subject line leads to the email being disregarded by possible donors or volunteers.  

Most importantly, fitting fundraising email subject lines really make your message stand out and make it through the inbox clutter, which could be crucial in the age where we are dealing with tons of information on a daily basis.

What are the best subjects for fundraising emails

There could be various potential subjects for a nonprofit email, depending on the goals and audience of the organization. Some common types might be:

• Fundraising appeals: an email calling for potential donors to support the organization’s mission and projects, both routine and one-off. 
• Quarterly or annual reporting: Nonprofits need to be transparent in fundraising campaigns since they deal with the money people have entrusted them with.
• Digital advocacy campaigns: encouraging supporters to take action on a particular issue or cause via email.
• Events (both digital and offline): an email promoting fundraising events, educational workshops, or other activities.
• Volunteer opportunities: seeking volunteers to help with projects or fundraising events.
• Newsletters: sending regular email updates about the organization and its endeavors.
• Thank-you emails: both after fundraising goals and after single donations, a thank-you email underlines the significance of every donation and makes the donor feel special. 

In crafting a subject for an email, any nonprofit should consider the needs and interests of its followers. A clear and honest subject line that leads into the content increases the chances that the email will get readers’ attention and the success of future campaigns.

How to write effective fundraising email subject lines

How can you compose effective subject lines for your fundraising emails? We have 7 tips to keep in mind:

Be mindful of the words you choose

Certain words and expressions can trigger spam filters or turn off readers. Here is what to keep in mind with your nonprofit fundraising campaigns: 

• Avoid certain words. For example, “need”, “free”, or all caps in the subject lines. Instead, opt for a clear and precise choice of words.
• Highlight the organization’s mission. Think of words like “future”, “tomorrow”, and “change”. 
• Use uplifting language. For example, “inspire” or “generosity” would be a good choice.
• Create a sense of unity with your subscribers by using “we”, “ours”, or “together”.

Keep it short and clear

Subject lines for fundraising emails should be short and to the point — this is a general digital marketing rule. 

Most email clients will only display the first few words of a subject line, so make sure your message is clear and concise. Aim for around 50 characters or fewer.

Numbers, especially, can tell a lot. For example, writing “85%” is more impactful than “almost done”. Indicating the amount of money raised is also a good idea.

Begin with action verbs

When action verbs are the first ones of your subject line, it shows how the situation is urgent and encourages readers to do something immediately. Some examples of action verbs include “act now”, “donate”, “sign up”, or “register.”

Create a sense of urgency

Adding a sense of urgency to your subject lines can encourage readers to take action. Use words like “last chance,” “limited time,” or “today only” to create a sense that the email is urgent. Don’t be too emotional, though; being straightforward and honest about it is the key to fundraising.

Intrigue or surprise the subscriber

Intriguing or mysterious subject lines in the fundraising campaigns pique the reader’s curiosity and encourage them to open the email. However, try not to be too vague in your subject lines, as this can lead to frustration or mistrust. Negative emotions like these can interfere with future fundraising.

This subject line from Unicef grabs subscribers’ attention and makes them want to read the message. And when they click on it, this is what they see:

Ask compelling questions

Asking a question in your subject line captivates donors and encourages them to open the email. Just be sure to keep it connected to your nonprofit’s mission and fundraising goals — this is a must for a successful email subject line.

Personalize your message 

Using personalization in your subject lines, such as changing the recipient’s name or location, can make the email feel more relevant and increase the chances of it being opened. Imagine what your readers take close to heart, to make fundraising more successful.

Now that we’ve discussed some basic tips for writing good nonprofit email subject lines, let’s examine specific types of emails and examples of persuasive fundraising subject lines.

Avoid spam triggers and excessive punctuation

Your fundraising email might end up in the spam folder if you use email spam words. For example, a subject line in all caps like “LIMITED TIME” or excessive punctuation will definitely alert spam triggers of most email services. Even if by some miracle it lands in the inbox, there is almost a guarantee that your subscribers won’t open it.

A/B-test your subject lines

The best email practice there is — always test your subject lines. An A/B test in email marketing allows you to test two subject lines (or other email features) on a small group first, and then send the winning version to the rest of your email list. Alternatively, you can split your list into two groups and analyze your A/B test results to check which ones have better open and click-through rates and drive more donations.

What is the best time to send fundraising emails

Generally, the best days to send fundraising emails are Tuesdays and Thursdays. Wednesdays and Mondays also work. Weekends might not be an ideal sending time, so keep that in mind when creating your email schedule. As for time, it is recommended to send emails between 9 am and 12 pm.

This information comes with the warning. There are numerous studies and reports with supported theory on when to send your fundraising and marketing emails, but in reality, it heavily depends on the field, audience, and other factors. To learn more, check out our article on the best time to send an email.

Real-life fundraising email subject line examples

American Red Cross: a case study

Let’s look at how these principles are working in practice. The American Red Cross provides support to people affected by disasters of various natures. According to Milled’s data, in 2022, the organization sent 11 emails. Most of them were dedicated to event promotions with subject lines like:

• Heroes Among Us Gala 2022
• Join Us Virtually!
• Buy Your Tickets Now!

Notably, these are concise and informative. Two of the examples above use action verbs. Exclamation points at the end show how significant these events are. 

The only call to participate by working and contributing to the cause is straightforward. The subject line is: 

• Clara’s Council Volunteer Opportunity

There are two fundraising emails with these subject lines: 

• URGENT: Support hurricane response in Florida 
• Communities recovering from Hurricane Ian face a long, difficult path 

The first one follows all the best practices. The second one is longer than recommended, yet it creates interest and motivates readers to click on the email. Here’s what the email about people affected by Hurricane Ian looks like:

The American Red Cross’s overall approach to subject lines is very restrained. To make sure everything is appropriate for the cause and context, the organization uses neutral language and refrains from emojis, for example.

Charity: Water: a case study

Let’s examine another example. Charity: Water provides drinking water to people without resources. The charity sent close to 50 emails in 2022: that’s several messages each month. Notably, this nonprofit uses holidays and other occasions to remind people to contribute.

The other particularity of Charity: Water’s subject line writing style is the positive approach:

• You have a lot to celebrate!
• Good News: The odds are in our favor
• Women and girls can’t be stopped
• Good News: This win is for all of us 🥳

The copywriters at this charity also know how to entice their subscribers with just one sentence:

• I love stories like this one
• See the journey of your donation in this new video
• This is what we mean when we say water changes everything
• Let’s show the world dirty waters true colors this #WorldWaterDay

The playful tone and emojis, however, go together with more serious topics:

• The burden of dirty water on mental health
• Clean water moves mountains
• Time flies when you’re changing lives
• It has been an absolute rollercoaster over here.
• Giving Tuesday is once a year, but your impact could be generational

The charity also cleverly draws attention to time-sensitive matters:

• Set an alarm for 9 a.m. ET tomorrow
• We have 24 hours to change lives in Nepal
• Your support is critical to our work in Nepal

Overall Charity: Water has a complex and diverse subject line strategy. Combining the appeal to different emotions for maximum impact is the essence of their success.

The email design of this charity is minimalistic, with a focus on bright and expressive images:
