- E-mail is ideal for detailed offers, newsletters, invoices and B2B follow-up.
- Only e-mail people who gave you their address — bought lists burn your sender reputation.
- Every campaign needs a clear unsubscribe link; respect your mailbox's daily limit.
- Track opens, clicks and bounces, and clean your list.
1. Build a consent-based list
Customers, website form sign-ups and newsletter subscribers — never bought lists.
2. Prepare your domain
Send from your company domain with SPF, DKIM and DMARC set up, and ramp up gradually.
3. Respect daily limits
Microsoft 365 allows about 10,000 messages a day and Google Workspace about 2,000. Send within the limit and continue the next day automatically.
4. Write mail worth opening
A short, useful subject; personalisation; one clear call to action.
5. Unsubscribe is mandatory
Include an unsubscribe link and one-click List-Unsubscribe headers, and never e-mail people who opted out.
6. Measure and clean
Track opens, clicks and bounces; remove hard bounces.
Service and campaigns in one place
With the Klamna e-mail channel, your mailbox becomes conversations next to WhatsApp and calls, and campaigns send within daily limits with unsubscribes and tracking. Each e-mail address is added to your own package — see pricing.
