Quick Answer

Email deliverability is the ability of an email to successfully reach the recipient's inbox rather than being filtered into spam or rejected entirely. It measures how well your emails pass through spam filters and authentication checks to land in the inbox. Test your emails with MailMoxie before sending to identify and fix deliverability issues.

Quick Answer

Improve email deliverability by setting up proper DNS authentication (SPF, DKIM, DMARC), maintaining a clean email list, sending relevant content, monitoring sender reputation, warming up new IPs, and following email best practices. Test your emails with MailMoxie before sending to identify issues and ensure optimal deliverability. Regular monitoring and adjustments help maintain good deliverability over time.

Quick Answer

Email deliverability is affected by technical factors (SPF, DKIM, DMARC authentication), sender reputation, content quality, engagement rates (opens, clicks), list hygiene, IP reputation, domain reputation, and email infrastructure. Receiving servers evaluate all these factors to determine inbox placement. Test your emails with MailMoxie before sending to catch issues that could hurt deliverability.

Quick Answer

Email deliverability best practices include setting up SPF, DKIM, and DMARC authentication, maintaining clean email lists, sending relevant content, using double opt-in, monitoring engagement metrics, warming up new IPs gradually, avoiding spam triggers, testing your emails with MailMoxie before sending, and regularly monitoring deliverability metrics.

Quick Answer

Monitor email deliverability by tracking bounce rates, open rates, click rates, spam complaints, DMARC reports, sender reputation scores, and inbox placement rates. Test your emails with MailMoxie before sending to catch issues early, and use email service provider analytics, deliverability monitoring tools, and DMARC aggregate reports to identify problems.

Quick Answer

Check your DNS records for email deliverability by using MailMoxie's free DNS Record Checker tool. Enter your domain to instantly see your SPF, DKIM, and DMARC records, identify issues, and get recommendations for fixing authentication problems.

Quick Answer

For email deliverability, you need SPF records (authorize sending servers), DKIM records (email authentication), DMARC records (policy enforcement), and MX records (receive email). These records work together to authenticate your emails and prevent spam filtering. Check your DNS records with MailMoxie's free DNS Record Checker to verify they're configured correctly.

Quick Answer

Common DNS record issues that hurt email deliverability include missing SPF/DKIM/DMARC records, syntax errors, multiple SPF records, misaligned domains, and outdated records. These problems can cause emails to be rejected or marked as spam. Use MailMoxie's free DNS Record Checker to identify and fix these issues quickly.

Quick Answer

For Mailchimp, you need to add Mailchimp's servers to your SPF record using `include:servers.mcsv.net`, add a DKIM record provided by Mailchimp at `k1._domainkey.yourdomain.com`, and configure DMARC for policy enforcement. These records authenticate emails sent through Mailchimp and improve deliverability. Verify your DNS records are configured correctly using MailMoxie's free DNS Record Checker.

Quick Answer

For Klaviyo, add `include:klaviyo.net` to your SPF record, add Klaviyo's DKIM record at the selector they provide (typically `klaviyo._domainkey.yourdomain.com`), and configure DMARC for email authentication. These records ensure emails sent through Klaviyo are properly authenticated and reach the inbox. Check your DNS records with MailMoxie's free DNS Record Checker to verify they're set up correctly.

Quick Answer

For SendGrid, add `include:sendgrid.net` to your SPF record, add SendGrid's DKIM record at `s1._domainkey.yourdomain.com` (or the selector SendGrid provides), and configure DMARC. These records authenticate emails sent through SendGrid's infrastructure and prevent spam filtering. Verify your DNS configuration using MailMoxie's free DNS Record Checker.

Quick Answer

For Google Workspace, add `include:_spf.google.com` to your SPF record, add Google's DKIM record at `google._domainkey.yourdomain.com`, configure DMARC, and set MX records to Google's mail servers (aspmx.l.google.com). These records authenticate emails and ensure proper email delivery. Check your DNS records with MailMoxie's free DNS Record Checker to ensure they're configured correctly.

Quick Answer

For Office 365, add `include:spf.protection.outlook.com` to your SPF record, add Microsoft's DKIM record at `selector1._domainkey.yourdomain.com`, configure DMARC, and set MX records to Office 365 mail servers (yourdomain-com.mail.protection.outlook.com). These records authenticate emails and ensure proper delivery. Verify your DNS records are set up correctly using MailMoxie's free DNS Record Checker.

Quick Answer

Email accessibility is designing emails that can be read and used by people with disabilities, including those using screen readers, keyboard navigation, or assistive technologies. Accessible emails benefit everyone and are required by law in many regions.

Quick Answer

Make emails accessible by adding alt text to images, using proper heading structure, ensuring sufficient color contrast, writing descriptive link text, including plain text versions, and testing with screen readers. Follow WCAG guidelines for best results.

Quick Answer

Email accessibility best practices include adding descriptive alt text to images, ensuring sufficient color contrast (4.5:1 for text), using proper heading hierarchy, writing descriptive link text, including plain text versions, and testing with screen readers.

Quick Answer

Common email accessibility issues include missing alt text on images, insufficient color contrast, image-only emails without text alternatives, unclear link text, and missing plain text versions. Fix these issues to make emails accessible to all recipients.

Quick Answer

Dark mode affects emails by inverting color brightness values—light backgrounds become dark, dark text becomes light, while images don't invert. Gmail's mobile apps aggressively invert colors and ignore dark mode media queries, which can break email designs.

Quick Answer

Gmail breaks emails in dark mode by inverting brightness values of all coded colors, ignoring the dark mode media query on mobile apps, and applying inconsistent inversion. This causes white backgrounds to turn dark, transparent logos to vanish, and text contrast to become unpredictable.

Quick Answer

Make emails work in dark mode by using real text instead of text in images, avoiding text on background images, preparing both light and dark logo versions, using dark mode media queries for Apple Mail, choosing midtone colors, and testing in the actual Gmail app on iOS and Android.

Quick Answer

Dark mode email best practices include using real text instead of text in images, avoiding text on background images, preparing light and dark logo versions, using dark mode media queries for Apple Mail, choosing midtone colors that invert gracefully, and testing in Gmail apps on iOS and Android.
