Some customers may notice a "Sent on Behalf Of" message when sending emails through Shape. This is specific to Outlook Exchange and does not appear in Gmail, Outlook 365, Yahoo, or most other email clients. Let’s break down why this happens, what it means, and how Shape handles email sending.
🔍 What Causes the "Sent on Behalf Of" Message?
Different email clients handle email headers differently. Outlook Exchange is more explicit in displaying the "sent on behalf of" message when an email is sent via a third-party system (such as a CRM, marketing platform, or email automation tool).
Shape does not send emails directly through your personal Outlook or Gmail account. Instead, it uses secure and compliant SMTP email servers to ensure proper email delivery, tracking, and authentication.
📌 Important to Note:
✅ Only Outlook Exchange shows "Sent on Behalf Of."
✅ Gmail, Outlook 365, Yahoo, and other clients do NOT display this message.
✅ This does NOT affect deliverability or email security.
⚖️ How Shape Compares to Other CRMs
Some CRMs send emails directly through your personal Gmail or Outlook account, but this can cause serious issues, including:
⚠️ Sending Limits & Spam Flags: Personal email providers strictly limit sending volume. Sending high volumes of emails can lead to account suspension, blocked emails, or spam filtering.
⚠️ Deliverability Issues: Bulk emails and automated campaigns sent through personal accounts often get flagged as spam, reducing effectiveness.
⚠️ Lack of Email Authentication: Without proper SPF, DKIM, and DMARC authentication, emails may not be verified as legitimate senders, further affecting deliverability and security.
🔹 What Shape Does Instead:
✅ Uses compliant SMTP servers to send emails securely.
✅ Implements SPF, DKIM, and DMARC authentication to improve email security and trustworthiness.
✅ Supports bulk emails, marketing campaigns, 1:1 messages, and transactional emails while maintaining high deliverability rates.
✅ Provides detailed analytics on email performance (opens, clicks, bounces, unsubscribes).
🔑 Why Does Shape Use SMTP for Email Sending?
Using dedicated email servers instead of personal email accounts ensures stability, compliance, and better results. Here's why:
🛡️ ✅ Compliance & Security – Meets regulatory requirements and protects against unauthorized email sending.
📊 ✅ Email Tracking & Analytics – Get insights into email opens, clicks, bounces, and unsubscribes.
📩 ✅ Higher Deliverability Rates – Emails are sent from authenticated servers, reducing spam filtering.
📅 ✅ Flexibility for Automation – Supports drip campaigns, bulk emails, and transactional messages seamlessly.
🔎 Final Takeaway: "Sent on Behalf Of" is Normal & Harmless
📌 The "Sent on Behalf Of" message only appears in Outlook Exchange and does NOT impact:
✔️ Email deliverability
✔️ Security & authentication
✔️ Your ability to send or receive emails through Shape
Using Shape’s secure SMTP email system protects your domain reputation, improves deliverability, and ensures compliance with industry standards.
