## Guides
- [What Sending an Email Means](https://mailrith.com/guides/what-sending-means.md): Mailrith prepares the campaign, your email delivery service sends the email, and inbox providers decide where the message lands.
- [Email Types and Sender Separation](https://mailrith.com/guides/email-types-and-sender-separation.md): Marketing, transactional, operational, and personal email should not always use the same sender setup.
- [Choose the Right Sending Method](https://mailrith.com/guides/choose-the-right-send.md): Use broadcasts for one-time messages, sequences for planned follow-ups, and automations for behavior-based journeys.
- [Plan Before You Write](https://mailrith.com/guides/plan-before-writing.md): A short plan keeps the email focused and prevents last-minute mistakes with subscribers, the offer, and timing.
- [Prepare the Sender Identity](https://mailrith.com/guides/prepare-sender-identity.md): Choose a sender name, sender email, reply-to address, and verified domain that match the trust you want subscribers to have in your email.
- [Keep Permission and Compliance Simple](https://mailrith.com/guides/permission-and-compliance.md): Send to people who expect your email, identify yourself clearly, and make unsubscribing easy.
- [Protect List Quality](https://mailrith.com/guides/protect-list-quality.md): A smaller list of people who want your emails is better than a large list of people who ignore or reject your emails.
- [Email Delivery Services](https://mailrith.com/guides/smtp-and-delivery-providers.md): An email delivery service sends your email, while Mailrith manages subscribers, campaigns, and follow-up.
- [Connect and Test an Email Delivery Connection](https://mailrith.com/guides/connect-and-test-provider.md): Create a Mailrith delivery connection, save the email delivery service credentials, assign the connection to the correct workspace, and send a test email.
- [Sender Domains and Email Authentication](https://mailrith.com/guides/sender-domains-and-authentication.md): Your sender domain is what inbox providers learn to trust. Authentication proves that your email delivery service is allowed to send email for your domain.
- [From, Reply-To, and Return-Path](https://mailrith.com/guides/from-reply-to-and-return-path.md): An email can include several sender-related addresses. Each address has a separate role for delivery, authentication, or replies.
- [DNS, PTR, and Reverse DNS](https://mailrith.com/guides/dns-and-reverse-dns.md): DNS records identify your domain. Reverse DNS helps inbox providers check that a sending IP address has a valid hostname.
- [Email Headers and Message Format](https://mailrith.com/guides/email-headers-and-message-format.md): Message headers, MIME structure, and basic formatting rules help inboxes read, display, and trust an email.
- [SPF](https://mailrith.com/guides/spf.md): SPF is a DNS record that lists the servers and services that may send email for your domain.
- [DKIM](https://mailrith.com/guides/dkim.md): DKIM adds a signature to each email so inboxes can confirm that an approved domain accepted responsibility for the message.
- [DMARC](https://mailrith.com/guides/dmarc.md): DMARC tells inboxes how to handle a message that uses your domain but does not pass aligned SPF or DKIM checks.
- [DMARC Alignment](https://mailrith.com/guides/dmarc-alignment.md): DMARC alignment checks whether SPF or DKIM authentication uses the same domain family as the domain subscribers see in the From address.
- [TLS and Secure Sending](https://mailrith.com/guides/tls.md): TLS encrypts email while it moves between mail systems. Bulk senders are now expected to use TLS.
- [MTA-STS and TLS Reporting](https://mailrith.com/guides/mta-sts-and-tls-reporting.md): MTA-STS and TLS reporting are advanced controls for domains that need stronger protection for inbound email transport.
- [ARC and Forwarded Email](https://mailrith.com/guides/arc-and-forwarding.md): ARC helps forwarding services preserve email authentication results when forwarding breaks SPF or changes a message.
- [Sender Reputation and Spam Rate](https://mailrith.com/guides/sender-reputation-and-spam-rate.md): Sender reputation is the trust inbox providers build from your authentication, sending history, volume, complaints, and subscriber behavior.
- [Dedicated and Shared Sending IPs](https://mailrith.com/guides/dedicated-and-shared-ips.md): Shared IPs let many senders use the same sending infrastructure. Dedicated IPs place more reputation responsibility on one sender.
- [Sending Volume and Warmup](https://mailrith.com/guides/start-small.md): New senders should build trust gradually instead of sending a large campaign right away.
- [Blocklists and Link Reputation](https://mailrith.com/guides/blocklists-and-link-reputation.md): Inbox providers may distrust a sender because of the sending IP, domain, email delivery service account, or links in the email.
- [Tracking Domains, Links, and UTMs](https://mailrith.com/guides/tracking-domains-links-and-utms.md): Open tracking, click tracking, tracking domains, and UTM fields affect reporting. They can also affect whether subscribers trust your email.
- [Inbox Placement, Promotions, and Spam Folders](https://mailrith.com/guides/inbox-placement-promotions-and-spam-folders.md): Delivery means the receiving system accepted the message. Placement means where the inbox shows the message.
- [One-Click Unsubscribe and Opt-Outs](https://mailrith.com/guides/one-click-unsubscribe.md): Marketing emails should make unsubscribing easy. Bulk sender rules also expect fast, simple unsubscribe handling.
- [Bounces](https://mailrith.com/guides/bounces.md): A bounce means an email could not be delivered. Repeatedly sending to bad addresses can hurt future delivery.
- [Spam Complaints](https://mailrith.com/guides/spam-complaints.md): A complaint means a subscriber marked your email as spam. Inbox providers treat complaints as one of the strongest negative signals.
- [Complaint Feedback Loops and ARF](https://mailrith.com/guides/complaint-feedback-loops-and-arf.md): Feedback loops tell senders when subscribers mark email as spam. These reports usually come from an email delivery service or mailbox provider.
- [Suppression Lists and Subscriber Status](https://mailrith.com/guides/suppression-lists.md): Suppression protects people who should not receive normal marketing email, including unsubscribed, bounced, or complained subscribers.
- [BIMI](https://mailrith.com/guides/bimi.md): BIMI can show a brand logo in some inboxes, but logo display depends on strong authentication and inbox support.
- [Build the Subscriber List](https://mailrith.com/guides/build-the-audience.md): Subscribers are people, tags describe subscribers, custom fields store subscriber details, and segments choose who matches the rules today.
- [Use Segments and Exclusions](https://mailrith.com/guides/use-segments-and-exclusions.md): Include the people who should receive the email, and exclude the people who should not receive it.
- [Write the Subject and Preview Text](https://mailrith.com/guides/subject-and-preview.md): The subject gets attention. The preview text gives subscribers another reason to open the email.
- [Write the Email Body](https://mailrith.com/guides/write-the-body.md): A good email has one main point, enough context, and one clear next step.
- [Design for Phones First](https://mailrith.com/guides/design-for-phones.md): Most subscribers scan emails quickly, so the email must be easy to read on a small screen.
- [Use Personalization Carefully](https://mailrith.com/guides/personalization.md): Personalization works well when subscriber data is reliable. It feels awkward when subscriber data is missing or wrong.
- [Choose Delivery Settings](https://mailrith.com/guides/delivery-settings.md): The delivery connection, reply-to address, tracking, UTM fields, and schedule should match the campaign purpose.
- [Test Like a Subscriber](https://mailrith.com/guides/test-like-a-subscriber.md): Test an email like a Subscriber by opening, reading, and clicking it on desktop and mobile before you send.
- [Send Now or Schedule](https://mailrith.com/guides/send-now-or-schedule.md): Send a campaign immediately only after the email, subscriber list, send time, and approvals are final.
- [Read the Results](https://mailrith.com/guides/read-results.md): After a campaign sends, review delivery, opens, clicks, unsubscribes, bounces, and complaints together.
- [Handle Bounces, Complaints, and Unsubscribes](https://mailrith.com/guides/handle-bounces-and-complaints.md): Delivery events help protect future sends by keeping risky addresses out of normal campaigns.
- [SMTP Errors, Deferrals, and Throttling](https://mailrith.com/guides/smtp-errors-deferrals-and-throttling.md): SMTP errors and email delivery service responses show whether a delivery problem is temporary, permanent, or caused by rate limits.
- [Troubleshooting Common Sending Problems](https://mailrith.com/guides/troubleshooting.md): You can narrow down most sending issues by checking setup, subscribers, content, email delivery service, and subscriber status.
- [Improve the Next Email](https://mailrith.com/guides/improve-next-email.md): Use each email send to learn one useful lesson and make the next campaign clearer.

## Key Takeaways
1. Good sending starts before the editor opens: know the goal, subscribers, sender, and timing.
2. A trusted sender and clean subscribers matter as much as the email design.
3. Every marketing email should be easy to understand, easy to act on, and easy to leave.
4. Test emails like a subscriber, especially on mobile.
5. After sending, use results to improve the next email instead of chasing one perfect campaign.
