MailShrine
Email Sanitization
Invalid, risky, and duplicates drop out before you open a campaign. Start with 200 credits/month.
How it works
Four moves. Bring the list in, read the marks, download what you want to keep, or open it in Email Marketing.
Paste addresses, or upload any file or a folder.
Each address is marked Good, Bad, or Not checked.
Take CSV, TXT, JSON, XML, Markdown, or Excel with your columns.
Start it in Email Marketing. That button does not send.
Features
The picture is the product. The short line is the job. The checks are what you walk away with.
Clean a list
Paste addresses, or upload any file or a whole folder. Then run the test. You see how many addresses were found before the clean starts.
The checks
You are not left with a single score. Every check shows Good, Bad, or Not checked, so you can see why a row stayed or fell out.
Results and download
A long list pages through so you can read it. Download the clean rows as CSV, TXT, JSON, XML, or Markdown. If you started from a spreadsheet, Excel is in the same menu and your original columns stay.
Email Marketing
Start campaign in Email Marketing hands the clean addresses to the campaign screen on the same account. It opens Email Marketing. It does not send the campaign.
Contacts
Folders here are the same folders as Email Marketing. After a clean, the folder can hold the file you brought in and a cleaned copy named sanitized- plus the original name.
One email
On Overview, type one address and check it. It is the same kind of check as a list, and it does not spend a credit.
Signup form
The signup form asks for a name, a phone number with a country, and an email. A hidden field catches simple bots. You get a row for each field: what passed, and why.
Your sending domain
Check the domain you send from. You get the DMARC record, if one is published, and whether that domain is on the public spam lists we look up.
API and form widget
Developers get a try-it sandbox that does not spend credits, keys for their own forms, a form widget, and a webhook when a clean finishes. The same check is ready in cURL, JavaScript, Python, PHP, Ruby, Go, Java, and C# — one email on a signup form, and a list clean.
The results table
Each address gets one row. A green check means that problem was not found. A red X means it was. A dash means that check did not run for the row.
| # | Label | Score | Blank | Duplicate | Format | Domain | Mailbox | Catch-all | Disposable | Role | Free email | Gibberish | Trap | Bounced | Typo | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | one@example.com | invalid | 0 | |||||||||||||
| 2 | user@gmail.com | clean | 88 | |||||||||||||
| 3 | info@acme.com | invalid | 0 | |||||||||||||
| 4 | temp@mailinator.com | risky | 60 |
The overall result for that row: clean, risky, invalid, unknown, mailbox full, or disabled.
How safe the address looks, as a number. Higher is safer. A hard failure is 0.
The row had no address. A check means an address was there. An X means the row was empty.
The same address already appeared earlier in this list. An X means it is a repeat.
The address is shaped like an email. An X means the syntax is broken, so later checks are skipped.
The domain has a mail server. An X means no mail server was found. A dash means this lookup did not run.
The mail server accepted that mailbox. An X means it rejected it, the box is full, or the account is disabled. A dash means it was not probed.
The domain accepts mail for any name, so a real mailbox cannot be confirmed. An X means it is a catch-all.
A temporary inbox, such as a throwaway provider. An X means the domain is disposable.
A shared address such as info@, admin@, or support@, not one person. An X means it is a role address.
A free provider such as Gmail, Yahoo, or Outlook.com. That is a risk flag, not a broken address.
The part before the @ looks like random characters rather than a name. An X means it looks made up.
The address looks like a spam trap or another toxic address. An X means it matched.
This address has bounced on a previous send we know about. An X means it has bounced before.
The domain looks like a misspelling of a known provider. We show “Did you mean …” when we can.
Support
Support is a form in the app: subject, priority, and the message. Tickets go to the Email Sanitization queue. The aim is a reply within 24 hours on business days.

Marks follow public product pages and can change. Partial means only part of that job — for example a file export that is not an Excel round-trip of your original columns, or an email widget that is not a name, phone, and bot-field signup form.

FAQ
Credits, the free checks, files, the signup form, your sending domain, and what happens when you open a campaign.
New accounts start with 200 credits per month. That free allowance refills every month. On a full list clean, one credit pays for one billable address. Duplicates in that list are free. An address that only fails the format check is free. A result we could not confirm — a timeout, a greylist, or a domain lookup that did not finish — is free. You are charged for a check that completed, including a domain that cannot receive mail.
The one-email check on Overview is free. The try-it sandbox on the API page is free, and it does not spend credits. Duplicates, format-only failures, and unknown results on a list are free. A full list clean spends credits on the billable addresses.
Name, phone, and email. The phone field includes a country so the number is checked with the right dialing code. The email runs the same kind of check as a list. A hidden field catches simple bots. You get a result row for each field. The sandbox checkbox on that screen stays free.
It looks up DMARC for the domain you send from, and it checks that domain against public DNS spam lists. You see the record, the policy, and whether each list says listed or not listed. It does not send mail.
Any file, or a folder of files. We read the email addresses out of what you upload, then you run the test. Paste works the same way if you do not have a file.
Yes, when the list came from a spreadsheet. Excel appears in the download menu for that job, and the file keeps the original columns plus the clean result. CSV, TXT, JSON, XML, and Markdown are available on every finished clean.
No. Start campaign in Email Marketing opens Email Marketing with the clean addresses. You still write the message and send it there. Email Sanitization does not send the campaign.
No. Sanitization for contacts used directly in MailShrine Email Marketing campaigns is included — there is no separate sanitization charge for those campaign contacts. Standalone Sanitization credits apply when you clean lists outside that campaign workflow, export cleaned lists independently, or use API and other sanitization workflows.
Open Support in Email Sanitization and submit a ticket with a subject, a priority, and a message. Tickets go to the Email Sanitization queue. The aim is a reply within 24 hours on business days. You can also email support@mailshrine.com.
