Because this link is shared externally, it’s important to treat it as a permanent address.
⚠️ Why your subdomain matters
Once your RSVP link has been sent to guests, it becomes the pathway for all responses.
📬 Guests use this link to submit their RSVP
🌍 It connects directly to your website and guestlist
🔄 RSVP responses rely on this link staying the same
Changing the subdomain after sharing it will break that connection.
🚫 What happens if you change it after sending RSVPs
If the subdomain is edited after invitations or RSVP links have been sent:
❌ Previously shared links will no longer work
😕 Guests won’t be able to submit their RSVP
📉 Responses may be missed or delayed
📩 Guests may contact you thinking something is broken
This can create unnecessary confusion and follow-up.
✅ Best practice before sending RSVPs
To avoid issues, it’s best to finalise your subdomain early.
✍️ Choose your subdomain before sharing your RSVP
🔍 Double-check spelling and formatting
🧪 Test the link to make sure it works as expected
Once confirmed, you can confidently share it with guests.
🔒 When it’s safe to edit your subdomain
🛠️ Before your RSVP link is shared publicly
📝 While your site is still in draft or setup mode
After RSVPs have been sent, the subdomain should remain unchanged.
⭐ The bottom line
Your URL subdomain is a critical part of your RSVP and website experience.
Changing it after sending RSVPs will break the link and prevent guests from responding. Lock it in early, test it once, and keep it consistent to ensure a smooth, stress-free RSVP process.
