Understand sending and list rules

Buying a sending allowance and having a suitable list are separate matters. Check these rules before choosing a package or importing a new list.

How do sending limits work?

Are there daily or hourly limits?

Standard paid packages have no daily sending limit. Annual volume packages have no daily, weekly or monthly cap. You can send as many emails as your package allowance covers.

The standard daily trial limit is 250 emails. Check the allowances shown in your account.

How should I start sending to a new list?

Run a bounce test on your list first. Start with recipients who recently agreed to receive your marketing emails and recognise your brand. Increase the audience in small groups while monitoring bounces and spam complaints.

Which lists are accepted?

Can I send cold emails?

No. Recipients must have given permission to receive your marketing emails. Do not send to bought, rented or scraped addresses. Keep the source and date of consent. Read the full Anti-Spam Policy.

Does verification replace consent?

No. Verification checks whether an address is technically reachable. It does not measure permission or interest, and it cannot guarantee that nobody will complain.

What happens before sending?

How does a free list bounce test differ from full list cleaning?

The free bounce test estimates your list’s bounce risk using known results and a random sample of up to 250 email addresses. It does not check every address, but gives you an indication of the list’s overall condition.

Full verification cleans the entire list and shows the results on the same screen. It uses email verification credits, which you can buy from your account.

Invalid addresses are blocked. Follow Verify and clean your email list.

What should I do with the bounce test result?

The result appears on screen when the bounce test finishes. If the estimated bounce rate is below 5%, you can use the list without cleaning it. If it is above 5%, clean the list to exclude invalid email addresses from your send.

Sending waits while a list check involving the intended recipients is running.

When is sending stopped?

What triggers an automatic review?

Hard bounces and spam complaints are assessed separately. Reaching either threshold is enough.

Result	Review, sending held	Sending stopped
Hard bounces	5% or more, below 10%	10% or more
Spam complaints	0.1% or more, below 0.5%	0.5% or more

Are addresses that hard bounce automatically excluded?

Addresses that hard bounce or report spam are added to the block list. They are excluded from future email campaigns. Unsubscribed contacts are also excluded from the audience. Do not reimport contacts to remove a block.

Which results can I review?

What do reports include?

You can review sends, opens, clicks, hard and soft bounces, spam complaints and unsubscribes. Bounce reasons and unsubscribe explanations are also available. Provider breakdowns include Gmail, Outlook and other services.

Where can I see a contact’s interactions?

Open the contact’s profile and select Activity. The timeline shows email sends, opens, link clicks, bounces and unsubscribes in date order. You can see when and how the contact interacted with your brand in one place.

What can the API do?

Paid packages include API access to manage contacts and list memberships, and read blocked addresses and campaign reports. Webhooks send supported events to your system. Campaigns can only be sent directly from the app.
