Email sending limits
Cloomba sends two kinds of email, and only one of them is limited.
Automatic emails — ticket confirmations, RSVP confirmations, reminders, cancellation notices — go out on their own when something happens. They are never limited and never count towards any allowance. Your guests always get their tickets.
Emails you choose to send — invitations and event updates — go out because you pressed Send. Those are the ones with limits, and this page explains how they work.
Why limits exist
When someone marks an email as spam, mailbox providers like Gmail trust the sender a little less — and on a shared platform, the sender is Cloomba. A single careless sender blasting a bought address list could push ticket confirmations into spam folders for every organiser on the platform.
The limits below protect that shared trust. If you email people who want to hear from you, you will most likely never run into them.
The monthly allowance
You can send up to 500 emails per calendar month, counted per recipient — an update sent to 40 guests uses 40. Invitations and event updates both count; automatic emails never do.
A single CSV import is capped at 5,000 rows.
Reaching people who don't know you yet
Someone belongs to your audience if they have RSVP'd to any of your events or follow you on Cloomba. Emailing your audience only draws on the monthly allowance above — inviting the sixty people who came last time never touches any other limit. Event updates go only to registered guests, so they are always in this category.
Everyone else counts as new to you, and a second, smaller allowance applies to them. Having a Cloomba account is not the same as knowing you: an invitation to a stranger counts as new even if they already use Cloomba.
The new-people allowance grows with your track record. You start with 100 new-people invitations per 30 days. Every event you have actually run — with a group of confirmed guests — adds another 100, up to 500 per 30 days. Higher limits are available on request.
What happens at a limit
The send is blocked as a whole — nothing goes out, and you see a message explaining which limit you hit. We never send half of your list and quietly drop the rest, so you always know exactly who has been emailed.
If you hit a limit with a genuine audience waiting, contact us and tell us about your events. Raising a limit for a real organiser is free and quick — the limits exist to stop scraped address lists, not community builders.
You confirm you have permission
Before invitation emails go out, you confirm that the people on your list have agreed to hear from you. This is a legal requirement under GDPR, not a formality. Never upload purchased or scraped address lists: the people on them file spam complaints, and complaints are what pause your sending.
Unsubscribes, bounces, and complaints
Every invitation and event update email contains an unsubscribe link, and Cloomba enforces the outcome for you:
- Unsubscribed — anyone who unsubscribes from your emails is skipped automatically on every future send, even if you re-import their address. You see the skip count before sending.
- Muted — Cloomba users who switched invitation emails off in their notification settings are skipped too, and don't count against your allowance.
- Bounced or complained — addresses that don't exist, or whose owners marked an email as spam, are never emailed again.
- Update opt-outs — a guest can unsubscribe from one event's email updates and still see the updates in the app.
If several recipients mark your emails as spam in a short period, your sending is paused automatically until we have looked into it together — contact us to resolve it.
