Deliverability of Emails

The deliverability of email is mainly dependent of two factors:

1. Quality of address lists
2. Quality of email content

If either one of those factors is not up to par this will result in email bounces and/or complaints. Apart from a lower response rate this could even prevent you from being able to send out emails. This is determined by the Email Service Provider (ESP).

Email Bounce and Complaint thresholds

To facilitate your goal of reaching your desired audience Survalyzer works with the highly trusted ESP AWS. This means the following thresholds are in place.

Bounce Rate

• Your bounce rate should remain below 5%. If your bounce rate exceeds 5% you will receive a warning.
• If your bounce rate exceeds 8% the ability to send emails will be disabled.

Complaint rate

• Your complaint rate should remain below 0.1%. If your complaint rate exceeds 0.1% you will receive a warning.
• If your complaint rate exceeds 0.4% the ability to send emails will be disabled.

Best practices

To increase the chances of a successful response rate you can use the following guidelines.

1. Only use trusted data sources obtained through opt-in for email distributions.
2. Use positive subject lines.
3. Specify why the recipient receives the email.
4. Use a familiar sender name, “From” or “Reply-to” email address.
5. Do not use a noreply email address
6. Make sure the link to the survey is working and do not use link shorteners.
7. Do not use CAPS LOCK, a red font, or a lot of exclamation marks (!)
8. Use a tools such as Blogiestools to scan the content of your message for ‘spam trigger words’ and replace highlighted words.
9. Send a test email using Mail Tester to determine the quality of the email.
