The scope depends on the tool and its settings. An unsubscribe or permanent delivery failure can be a reason for suppression.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1.webp\" alt=\"A suppressed contact card is left out of a mailing.\" class=\"wp-image-2191\" srcset=\"https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1.webp 1200w, https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1-300x200.webp 300w, https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1-1024x683.webp 1024w, https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1-768x512.webp 768w, https:\/\/www.mailfino.com\/wp-content\/uploads\/2026\/11\/mailfino-glossar-sperrliste-v1-18x12.webp 18w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How does a suppression list differ from a blocklist?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A suppression list applies when the sender selects recipients. Receiving mail servers can use an email blocklist to assess messages based on the sending IP address or domain. The lists operate at different points in the sending process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Example after a reimport<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An unsubscribed address appears again in a later export file. Check that the import preserves existing suppression records and that the address is still excluded from the planned mailing. In mailfino, a suppressed address is excluded from newsletter sends.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Further reading<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><a href=\"\/en\/glossar-email-blacklist\/\">What is an email blocklist?<\/a><\/li>\n\n\n\n<li><a href=\"\/en\/newsletter-listenhygiene\/\">What is email list hygiene?<\/a><\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"\/en\/glossar\/\">Back to the email marketing glossary<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Eine Sperrliste erfasst Adressen, die ein Versandtool bei bestimmten oder allen k\u00fcnftigen Aussendungen ausschlie\u00dft.
