Check your list before you send, so fewer messages bounce. A bounce is a message that comes back because it couldn't be delivered. Tomba checks the addresses, and your own email tool does the sending.
Before you start
You need verification credits. The Free plan has none, so you need a paid plan or a credit pack.
Verify your list
Step 1. Get your list ready. You can paste it with one email per line, or upload a CSV file, which is a simple spreadsheet file. A list can have up to 20,000 rows, and a file can be up to 4 MB.
⚠️ Important: .xlsx, .xls, .numbers and .ods files are refused. Save your spreadsheet as CSV first.
Step 2. Open Email Verifier in Bulks and select New bulk. A bulk runs one tool on a whole list at once.
Step 3. Type a List name. Paste your emails under Enter the emails, or upload your file and check Match your columns. Then select Start bulk.
Step 4. When the bulk finishes, select Download CSV. Choose Valid only to get just the good addresses, or All results to see every row. Then select Download CSV in the window.
💡 Tip: Both files cost the same, and only your first download is charged. You can get the other file afterwards for free.
What the results mean
Result | What it means | What to do |
Valid | Mail to this address should be delivered. | Send. |
Accept-all | The company's mail server accepts mail for any address, so we can't confirm this mailbox. | Send with care. |
Risky or Unknown | The check didn't give a clear answer. | Send with care, or verify again later. |
Invalid | Mail to this address will bounce. | Remove it from your list. |
A disposable address is a temporary one that people use for a short time. Treat it as invalid.
Send soon after you verify
If a Valid address hard-bounces, you can claim 1 search credit back. A hard bounce means the mail server rejected the message for good, because the address doesn't exist.
The claim only covers addresses you sent to within 30 days of verifying them. You must also send from a domain set up with SPF, DKIM and DMARC. These are email settings that prove you're allowed to send from your domain. Whoever manages your company email can tell you if they're in place.
💳 Credits: 1 verification credit per row, charged on your first download. Disposable addresses aren't charged.
Common questions
Does Tomba email the people on my list?
No. Tomba checks each address without sending anything, and it has no sending feature.
Can I verify the same list again?
Yes, but it uses credits again. Repeating a search is usually free, but that rule doesn't cover bulks.
What if my list has more than 20,000 rows?
Split it into smaller lists. Rows beyond the limit aren't processed. You can run 2 Email Verifier bulks at the same time.
