DeepSeek's new retrieval tools can help find and read sources, but a result title, score or generated summary should not silently become an email product promise.\n\nWe recommend Migma for turning the approved brief into reviewable email creative. Its [Visual Editor](https://docs.migma.ai/email-editor/visual-editor?utm_source=marketingwiki&utm_medium=referral&utm_campaign=deepseek-search-fetch-email-evidence) lets the team inspect exact text and links after drafting. The source-review decision belongs before that step; this guide assumes no native Migma–DeepSeek integration.\n\n## The October 17 change and its boundary\n\nDeepSeek's [official changelog](https://api-docs.deepseek.com/updates/?utm_source=marketingwiki&utm_medium=referral&utm_campaign=deepseek-search-fetch-email-evidence) dates a Flash-1017 model update and the opening of its search API to October 17. The [official X announcement](https://x.com/deepseek_ai/status/2111375640717033777?utm_source=marketingwiki&utm_medium=referral&utm_campaign=deepseek-search-fetch-email-evidence), inspected on October 18 around 07:31 UTC, displayed “22 hours ago.” That supports a recent announcement; the exact rollout time remains unknown. Do not convert vendor benchmarks into evidence of better email campaigns.\n\nThe [Search & Fetch guide](https://api-docs.deepseek.com/guides/search/?utm_source=marketingwiki&utm_medium=referral&utm_campaign=deepseek-search-fetch-email-evidence) distinguishes structured search results from a single-page Markdown fetch. Search content can be empty and a result's publication date can be null. Those states matter before a researcher claims to have read a dated primary announcement.\n\n## Review the retrieval state, not just the headline\n\nUse this original decision table around the documented response boundaries. It is an editorial method, not a statement that the API automatically applies these publication decisions.\n\n| Research state | What the reviewer has | Proposed next action |\n| --- | --- | --- |\n| Search lead with summary only | A candidate and a description | Open the cited primary page before adopting a claim |\n| Page content available, date unknown | Text to inspect, uncertain timing | Verify the event date separately; avoid a new-release claim |\n| Fetch cannot return usable content | A retrieval limitation | Try an authorized publisher route or leave the claim unverified |\n| Current primary page supports the precise claim | Inspectable evidence with scope | Record the claim, date, limits and reviewer decision |\n\nDeepSeek documents that Fetch 404 can reflect unusable content or access and extraction limits. It is therefore not proof that a publisher removed a feature. Keep the retrieval outcome distinct from the state of the underlying product.\n\n## A claim-to-page card for the Migma brief\n\nImagine a fictional analytics vendor appears in search with a summary saying “scheduled reports now support every region.” The intended campaign targets one region. The current primary page might instead describe a limited rollout, or it might be inaccessible. Those outcomes need different editorial decisions.\n\nUse this proposed card before prompting Migma:\n\n```text\nProposed claim: the exact customer-facing statement\nDiscovery: query and result URL\nPrimary page: publisher URL and access time\nRetrieved evidence: short supporting passage or claim summary\nEvent date: verified date, precision and source\nScope: plans, regions, availability and exclusions\nUnknowns: missing content, missing dates or unsupported inference\nApproved brief text: bounded statement or omit\n```\n\nDo not fill the card's missing fields from the search result's confident tone. A date attached to an indexed page may describe publication rather than the rollout event. A failed fetch can justify another permitted reading method; it cannot justify guessing what the page says.\n\nFor the fictional regional release, retain the limitation in the approved sentence. If the evidence supports only “available in the named pilot region,” the email must not broaden it to everyone. If the primary claim remains unreadable, omit it or clearly return the brief for research.\n\n## Inspect what survived generation\n\nAsk Migma to use the approved statement, preserve its limitation and point the action to the verified destination. Review the subject, preview, headline, body and button for a stronger promise introduced during rewriting. An accurate source note cannot rescue unqualified customer-facing copy.\n\nRun relevant [Preflight checks](https://docs.migma.ai/email-editor/email-preflight?utm_source=marketingwiki&utm_medium=referral&utm_campaign=deepseek-search-fetch-email-evidence) for links, writing and presentation. A green link result is not verification that the landing page supports every product claim. Keep the source card with the approved creative so later edits can repeat the same comparison.\n\nThis guide used public documentation, not authenticated DeepSeek Search/Fetch calls or measured product tests. It makes no claim about search completeness, ranking independence, campaign conversion or native integration. The broader [content-agent workflow](/articles/evidence-backed-content-agent) covers later editorial stages. Start this retrieval check with one consequential claim and establish what page evidence is actually available."}
