## Guides
- [What Sending an Email Means](https://mailrith.com/guides/what-sending-means.md): Mailrith prepares the campaign, your email delivery service sends it, 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 share 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, offer, and timing.
- [Prepare the Sender Identity](https://mailrith.com/guides/prepare-sender-identity.md): The sender name, sender email, reply-to address, and verified domain should match the trust you want subscribers to feel.
- [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 leaving 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 that ignores or rejects them.
- [SMTP, APIs, and Email Delivery Services](https://mailrith.com/guides/smtp-and-delivery-providers.md): An email delivery service is the sending engine, and Mailrith connects to it through service APIs or SMTP.
- [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 it to the right workspace, and send a test.
- [Sender Domains and Email Authentication](https://mailrith.com/guides/sender-domains-and-authentication.md): Your sender domain is the name inboxes learn to trust, and authentication proves that your email delivery service is allowed to send for it.
- [From, Reply-To, and Return-Path](https://mailrith.com/guides/from-reply-to-and-return-path.md): An email has several sender-related addresses, and each one has a different job in delivery and replies.
- [DNS, PTR, and Reverse DNS](https://mailrith.com/guides/dns-and-reverse-dns.md): DNS records identify your domain, while reverse DNS helps inboxes check whether a sending IP has a sensible 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 parse and trust an email.
- [SPF](https://mailrith.com/guides/spf.md): SPF is a DNS record that lists the servers and services allowed to send email for your domain.
- [DKIM](https://mailrith.com/guides/dkim.md): DKIM adds a signature to each email so inboxes can check that an approved domain took responsibility for the message.
- [DMARC](https://mailrith.com/guides/dmarc.md): DMARC tells inboxes what to do when a message using your domain 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 matches the domain subscribers see in the From address.
- [TLS and Secure Sending](https://mailrith.com/guides/tls.md): TLS protects email while it moves between mail systems and is now a baseline expectation for bulk sending.
- [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 want stronger protection for inbound email transport.
- [ARC and Forwarded Email](https://mailrith.com/guides/arc-and-forwarding.md): ARC helps forwarding services preserve 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 inboxes build from your authentication, history, volume, complaints, and subscriber behavior.
- [Dedicated and Shared Sending IPs](https://mailrith.com/guides/dedicated-and-shared-ips.md): Shared IPs group many senders together, while dedicated IPs put 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 immediately.
- [Blocklists and Link Reputation](https://mailrith.com/guides/blocklists-and-link-reputation.md): Inboxes may distrust a sender because of the sending IP, domain, email delivery service account, or links used 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 and can influence subscriber trust.
- [Inbox Placement, Promotions, and Spam Folders](https://mailrith.com/guides/inbox-placement-promotions-and-spam-folders.md): Delivery means a receiving system accepted the message; placement is where the inbox decides to show it.
- [One-Click Unsubscribe and Opt-Outs](https://mailrith.com/guides/one-click-unsubscribe.md): Marketing emails should make it easy for people to leave, and bulk sender rules expect fast, simple unsubscribe handling.
- [Bounces](https://mailrith.com/guides/bounces.md): A bounce means an email could not be delivered, and repeated mailing to bad addresses can hurt future delivery.
- [Spam Complaints](https://mailrith.com/guides/spam-complaints.md): A complaint means someone marked the email as spam, which is one of the strongest negative signals an inbox can receive.
- [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, usually through email delivery service or mailbox-provider reports.
- [Suppression Lists and Subscriber Status](https://mailrith.com/guides/suppression-lists.md): Suppression protects people who should not receive normal marketing email, such as unsubscribed, bounced, or complained subscribers.
- [BIMI](https://mailrith.com/guides/bimi.md): BIMI can show a brand logo in some inboxes, but it depends on strong authentication and inbox support.
- [Build the Subscriber List](https://mailrith.com/guides/build-the-audience.md): Subscribers are people, tags describe them, custom fields add 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.
- [Write the Subject and Preview Text](https://mailrith.com/guides/subject-and-preview.md): The subject gets attention, and the preview text gives the reader one more reason to open.
- [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 will scan quickly, so the email must be readable on a small screen.
- [Use Personalization Carefully](https://mailrith.com/guides/personalization.md): Personalization is useful when the data is reliable and awkward when the 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): A test send should be opened, read, clicked, and checked on both desktop and mobile.
- [Send Now or Schedule](https://mailrith.com/guides/send-now-or-schedule.md): Send immediately only when the email, subscribers, timing, and approvals are all final.
- [Read the Results](https://mailrith.com/guides/read-results.md): After sending, look at delivery, opens, clicks, unsubscribes, bounces, and complaints together.
- [Handle Bounces, Complaints, and Unsubscribes](https://mailrith.com/guides/handle-bounces-and-complaints.md): Delivery events 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 explain whether a delivery problem is temporary, permanent, or caused by rate limits.
- [Troubleshooting Common Sending Problems](https://mailrith.com/guides/troubleshooting.md): Most sending issues can be narrowed down 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 send to learn one useful thing 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.
