Email hundreds of recipients, personally

Mailing sends your campaign through your own SMTP accounts and personalises every message with a name and a personal note. You follow the progress live, per campaign.

How Mailing works

  1. Create a campaign. Give it a name, a subject and a message — HTML with an optional text version — plus a sender name and reply-to address. Placeholders for first name, last name or a personal note can be clicked straight into the subject or the text; a preview shows the result with sample data.
  2. Add recipients. Import a customer group from the CRM app, upload a semicolon-separated CSV file, or enter addresses by hand. Duplicate and invalid addresses are skipped automatically.
  3. Start and follow. Mailing sends through the queue, spread across the linked SMTP accounts. The progress page refreshes every five seconds; pausing, resuming or cancelling is possible at any time.

Who it’s for

Control over your sending speed

Mail providers throttle accounts that send a lot in a short time. Mailing therefore keeps each account to a maximum of 30 emails per minute and rotates linked accounts round-robin. If every account is equally full, the queue waits briefly and then carries on automatically. Failed emails are retried up to three times; whatever still fails after that, you put back in the queue from a paused campaign.

Frequently asked questions

Do I need a separate mail server or mailing service?
No. Mailing sends through the SMTP accounts you've set up in the platform's Webmail app. Webmail is therefore required; the CRM app is optional and is only used to import recipients.
How does Mailing stop my mail provider from throttling me?
Each account has a limit of 30 emails per minute. Link several accounts and Mailing spreads the sending across them round-robin. If every account is at its limit, the queue waits briefly and then carries on automatically.
Which fields can I personalise?
Five placeholders: first name, last name, email address, full name, and a personal note per recipient. They work in both the subject and the message; unknown placeholders are flagged when you save.
What happens to emails that can't be sent?
Every email is retried up to three times, with a minute's pause in between. If it still fails after that, the recipient shows as failed in the list, with the error message next to it. From a paused campaign you can put all failed recipients back in the queue at once.
What format does my CSV file need?
Semicolon-separated, up to 10 MB, with a column called email or emailadres. Columns for first name, last name and a personal note are optional. After the import you see how many rows were added and how many were skipped.
