Personalize every client-facing email. Customize invoice messages, payment reminders, receipts, and estimate emails with your own voice, branding, and signature.
Try It FreeGeneric system-generated emails feel impersonal. Kantivo lets you rewrite the subject lines, body text, and closing remarks for every type of email you send -- invoices, payment reminders, receipts, and estimates. The result is communication that matches your company's tone, not a software vendor's default template.
Every template supports dynamic variables that automatically insert the correct customer name, invoice number, amount, and due date at send time. Write the message once, and it personalizes itself for every recipient.
Customize the message that accompanies each invoice delivery. Introduce the invoice, reference the project, and set clear payment expectations.
Overdue reminder emails that are polite but firm. Adjust the language for each stage -- friendly nudge, second notice, final reminder.
When a client pays, Kantivo can send a branded receipt confirming the transaction. Edit the thank-you message and include any follow-up instructions.
Send estimates and proposals with a professional cover message. Explain the scope, set a validity period, and invite the client to approve.
Use these placeholders in any template. Kantivo replaces them with the actual values when the email is generated, so every message is accurate and personalized without manual editing.

|---|---|---|
| {{customer_name}} | Customer's full name or business name | Acme Corporation |
| {{invoice_number}} | Invoice number | INV-2026-0042 |
| {{amount}} | Total amount due | $2,450.00 |
| {{due_date}} | Payment due date | April 15, 2026 |
| {{company_name}} | Your company name | Summit Design Co. |
| {{balance_due}} | Remaining balance after partial payments | $800.00 |
| {{payment_date}} | Date payment was received | March 28, 2026 |
Every outgoing email ends with your signature. Kantivo lets you build a professional email signature that includes your name, title, company, phone number, and website. The signature is applied consistently across all email types so clients always know who to contact.
Compose your signature with the fields that matter to your business. Include as much or as little as you need.
See exactly what your client will see before anything is sent. Preview any email template with sample data to verify layout, tone, and formatting.
If you manage more than one company in Kantivo, each company can have its own set of email templates and its own signature. A consulting firm and a retail shop probably communicate very differently -- now each can have messaging that fits its audience without switching between tools.
