Understand sending and list rules
Learn about sending limits, list checks, bounce and complaint thresholds, reporting and API access.
Buying a sending allowance and having a suitable list are separate matters. Check these rules before choosing a plan or importing a new list.
How do sending limits work?
Are there daily or hourly limits?
The monthly plan has no daily sending limit. You can send as many emails as your monthly allowance covers, and the allowance renews every month. A 12-month package can have a daily sending limit, which you are told when you buy it. Within that limit, you send as many emails as your package credits cover.
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 continues | 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 |
A review does not stop sending. The MailGraf team looks at the account, and the app shows a list-quality note on the Review step until the rate recovers. Sending stops only at the stop thresholds and reopens after the MailGraf team's check.
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.
For details, see Read a contact profile.
What can the API do?
Paid plans include API access to manage contacts, list memberships and tags, read each contact's engagement, add addresses to the block list, and read campaigns and their reports. Webhooks send supported events to your system. The API does not send campaigns. Campaigns are sent from the app, and an AI assistant you connect through MCP can also send and schedule them. See Assistant permissions and approvals.
Frequently asked questions
Does list verification prevent spam complaints?
No. Verification checks the technical state of an address. It does not prove that the recipient wants your emails or has given permission.
Does a paid plan include a daily sending limit?
The monthly plan has no daily sending limit: you send within your monthly allowance. A 12-month package can have a daily sending limit, which you are told when you buy it.
Can I send a campaign through the API?
No. The API manages contacts and lists and reads campaigns and their reports; it does not send campaigns. You send campaigns from the app. An AI assistant you connect through MCP can also send and schedule campaigns after showing you a review.
What happens when an account is placed under review?
Sending continues. The review is a signal for the MailGraf team; the app shows you a list-quality note, and we recommend verifying and cleaning your list before the next campaign. Only the stop thresholds pause sending.
