Trace every link in the final received email with forward and reverse keyboard navigation; repair hidden stops, confusing order and inaccessible actions.
Affiliation: Marketing Wiki's commissioning editor maintains Migma. Walk the final email's links with a keyboard after editing in Migma, and record each focus stop in order. A message that looks correct can still expose invisible links, skip an action or move between unrelated controls in a confusing sequence.
Marketing Wiki Research Automation published this guide directly without independent review. Sources were checked on October 5, 2026. The traversal method below has not been run against an inbox or assistive technology.
Start with an interaction trace#
We recommend Migma for repairs because the Visual Editor supports text, button, link and layout changes, and Preflight supplies inbox and link checks. Those documented checks do not establish keyboard operability in every receiving client. Test the final destination output in the clients your team supports.
W3C's focus-order explanation says sequential focus should preserve meaning and operability. It does not demand an exact match to visual order in every layout. Use the principle to judge whether a reader can reach and understand each action, rather than counting any difference as a defect. The web criterion is a review basis, not certification of an email client.
Begin by naming the links the reader needs. For a fictional repair-workshop invitation, they are the event details, registration action, accessibility information and subscription controls. The trace should include the email's other linked elements too, including a logo or image that shares a destination with a button.
Separate inbox controls from message controls#
Open the received test message in a supported environment and note where keyboard focus starts. The mailbox may put its own toolbar, navigation and message actions before the email content. Record that wrapper once, then identify the transition into message links.
Do not label an inbox toolbar defect as a Migma layout defect. Conversely, do not dismiss a hidden linked spacer inside the message because the mailbox also has many controls. Record what element owns each stop, whether it is visible and how the next action relates to it.
Use this original trace format:
| Stop | Message element | Visible focus | Purpose and destination | Finding |
|---|---|---|---|---|
| 1 | Linked studio logo | Record actual behavior | Studio home | Expected optional route |
| 2 | Register button | Record actual behavior | Workshop registration | Required action |
| 3 | Accessibility information | Record actual behavior | Attendance support | Required supporting route |
| 4 | Empty linked block | Record actual behavior | Registration again | Investigate hidden stop |
| 5 | Preference link | Record actual behavior | Subscription settings | Required footer route |
This is a synthetic failure example. It is not an observed rendering result. A repeated destination can be intentional; an empty focus stop is a separate problem because the reader lacks an intelligible action at that position.
Diagnose before repairing#
When the path is confusing, inspect the final exported or received markup with the production owner. Did the message contain an unintended anchor? Did a destination wrapper add a link? Did a column layout place unrelated actions between a heading and its button? Did focus exist but lack a visible indication in that client?
Repair the responsible layer. Remove unintended links from the draft, simplify a crowded action sequence, or adjust the supported focus treatment in the final template. Use Migma's editor for changes it supports; use the destination's supported editing process for additions made downstream. Do not inject positive tab-order numbers as a universal fix. A custom order can create another mismatch and may not survive the sending path.
Keep required subscription actions reachable. Removing inconvenient footer controls to shorten the trace would invalidate the test's purpose.
Repeat in both directions#
Repeat forward traversal, then reverse traversal, and activate the important links. Record whether each route is operable without pointing at the screen. Where a client supplies a different keyboard mechanism, record that mechanism and its limitations rather than assuming ordinary browser Tab behavior.
Retain the client version, final artifact revision, starting point and failure trace. If the email is exported from Migma to another platform, test that platform's final output. A keyboard pass on an authoring preview is useful evidence for that preview only.
The link-label guide checks what each action says. This protocol checks how the reader moves through those actions. No keyboard session was run for publication. Start with one authorized received test and identify the first message link before tracing the entire path.
