Be our guest at [EventName]
It’s simple, classic, and courteous.
“Be our guest” implies hospitality and value. Use this kind of subject line when hosting open houses, customer appreciation days, or community events.
It softens the request and sparks curiosity. It also pairs well with friendly preview text, such as “We’d love to see you there.”
Type: Invitation
Tone: Polite, inviting
We noticed your help, and we’re grateful
For example forum heroes answer questions at 2 a.m. just because. Calling that out boosts retention and turns lurkers into helpers.
Mention “noticed” to show you track contributions without sounding creepy.
Pair the email with a badge or discount code to encourage prosocial behavior.

Hands Needed for Saturday Pantry Shift
Type: Volunteer Request
Tone: community‑minded, urgent yet friendly
Why it works
Urgency drives opens. According to Porch Group Media, urgency in the subject line results in a 22% lift.
Pair that lift with vivid imagery, “hands”, and recipients picture themselves in action.
Mentioning Saturday narrows the commitment window and signals you respect their calendar.
Keep the body copy equally concrete: date, time, task, and a quick thank‑you.
This Subject Line Can Also Be:
- “Could you spare two hours Saturday?”
Quick favor, need two volunteers for [Event] this Friday
Type: Community, Volunteer Call
Tone: Friendly, upbeat, mildly urgent
Why this line works
The subject line phrase “Quick Favor” in this request email lowers the perceived effort, while “Two Volunteers” shows scarcity and encourages recipients to click.
Using urgent wording, such as “this Friday,” can increase open rates by about 22%.
Social proof lies in the details: If others have already volunteered, you may want to as well.
Placeholders let you slot event details and keep every send fresh.
When to use
Fire this kind of email three to five days before the event, after your broader sign‑up push.
Skip it if the volunteer list is already public; the “two” might contradict what folks see elsewhere.
Grateful to have you with us
Tone
Heartfelt, appreciative, brand-aligned
Why It Works
This line works well for new users, long-term customers, or contributors to your platform or product.
It’s emotionally loaded without being over the top. “Grateful” outperforms “thankful” in some A/B tests because it adds a slightly deeper layer of sincerity.
Pair this subject line with an email that recaps progress or acknowledges a milestone, like “You’ve been with us 100 days” or “You referred 3 new users.”
Example Email
Hi [First Name],
Every time you log in, read an article, or share feedback, you help shape this space into something better.
You might not always see the ripple effects, but they’re there. We’re grateful to have you with us.
Here’s a little snapshot of what your time here has helped build.
Reminder: RSVP for [event name] by [RSVP deadline]
Tone
Inviting, upbeat, timely
Why this line works
This is where structure beats cleverness.
You list the event. You list the deadline. That’s it. You’re not teasing or joking. You’re just nudging politely.
I like this one for team offsites, webinars, or even small celebrations.
Email subject lines that show a specific response deadline outperform vague reminders by up to 19%. It makes sense, you’re not leaving the RSVP open-ended, so people make faster decisions.
Example use
Send this 3 to 5 days before the cutoff. Then follow up with a “final call” subject line a day before the RSVP deadline.
