Does using AMPhtml in emails affect how ISPs deliver them to different folders?
Summary
What email marketers say12Marketer opinions
Email marketer from Campaign Monitor shares that high engagement rates (opens, clicks) signal to ISPs that your emails are wanted, positively influencing deliverability. Conversely, low engagement or high complaint rates can lead to emails being directed to the spam folder, irrespective of AMP usage.
Email marketer from EmailVendorSelection.com responds that implementing AMP for Email doesn't directly impact deliverability. Deliverability hinges on sender reputation, authentication, and engagement, not the email format. AMP is supported based on subscriber preference and provider capability, not deliverability.
Email marketer from HubSpot answers that maintaining a clean and engaged email list is crucial for deliverability. Sending emails to outdated, inactive, or purchased lists can result in high bounce rates and spam complaints, negatively affecting sender reputation and deliverability, regardless of whether AMP is used.
Email marketer from Validity answers that using AMP in emails doesn't automatically bypass spam filters or negatively affect deliverability. Deliverability is based on sender reputation and following best practices. AMP can enhance user experience, indirectly improving engagement metrics that influence deliverability.
Email marketer from Mailgun explains that inbox placement isn't solely determined by the use of AMP; it's influenced by various factors, including sender reputation, email authentication (SPF, DKIM, DMARC), engagement rates, and content quality. AMP can indirectly affect placement if it enhances user engagement.
Email marketer from Litmus shares that AMP for Email doesn't directly impact inbox placement. Inbox placement is determined by factors like sender reputation and email authentication, not the inclusion of AMP. AMP focuses on interactive content, which indirectly enhances engagement and thus deliverability.
Email marketer from StackOverflow user explains that AMP by itself doesn't trigger spam filters, but if your email content contains spam-like characteristics (e.g., excessive links, misleading subject lines) or if you have poor sender reputation, the email, including the AMP part, is likely to be filtered.
Email marketer from Email on Acid shares that poorly designed emails, regardless of whether they use AMP or not, can negatively affect deliverability. Emails with broken HTML, large image sizes, or spammy content are more likely to be flagged by spam filters.
Marketer from Email Geeks shares that to enable AMP, registration with receivers is needed, along with demonstrating good sender reputation. Violating this trust leads to spam. Sending AMP mail itself doesn't improve deliverability or folder placement.
Email marketer from ReturnPath responds that sending volume can influence how ISPs treat your email. Sending large volumes of email suddenly, without a warm-up period, can trigger spam filters and negatively impact deliverability, regardless of whether the emails use AMP or not.
Marketer from Email Geeks explains that 'open rates' measurement matters as AMP emails operate differently and go through different proxies. Neither of Uldis's theories are happening. People might use different email clients which might or might not fall back on html.
Email marketer from Reddit user shares that the perception of lower OR when sending AMP emails could be due to how AMP emails are handled by different email clients and proxies. Some clients might not support AMP, causing fallbacks, while others may load tracking pixels differently, leading to inaccurate open rate tracking.
What the experts say2Expert opinions
Expert from Word to the Wise shares that proper email authentication (SPF, DKIM, DMARC) is critical for inbox placement. Without proper authentication, ISPs may view emails as suspicious, leading them to be filtered into the junk folder. The presence of AMP in the email does not override the need for strong authentication.
Expert from SpamResource explains that deliverability to different folders heavily depends on sender reputation. If the IP address or sending domain has a poor reputation, emails are more likely to land in the spam or junk folder, regardless of whether they use AMP or not.
What the documentation says5Technical articles
Documentation from IETF outlines that using SPF (Sender Policy Framework) records is crucial for email deliverability. SPF records specify which mail servers are authorized to send emails on behalf of your domain. Incorrectly configured or missing SPF records can lead to emails being rejected or marked as spam.
Documentation from DMARC.org explains that DMARC (Domain-based Message Authentication, Reporting & Conformance) builds upon SPF and DKIM to provide a policy framework for email authentication. Properly configured DMARC policies can prevent email spoofing and phishing attacks, significantly improving deliverability by signaling to ISPs that the sender is legitimate.
Documentation from DKIM.org outlines that DKIM (DomainKeys Identified Mail) provides a method for verifying the authenticity of email messages. Properly implemented DKIM can significantly improve email deliverability by assuring ISPs that the email is not spoofed and originates from a legitimate source.
Documentation from Google Developers explains that to send AMP emails, you must adhere to strict security requirements, including SPF, DKIM, and DMARC authentication. Failure to meet these requirements will likely result in emails being flagged as spam or not rendering correctly, impacting deliverability.
Documentation from Microsoft outlines that using S/MIME for email encryption can affect deliverability if not implemented correctly. Misconfigured S/MIME settings can cause emails to be flagged as suspicious by some ISPs, thus landing in spam or junk folders.
