Case Study: WhichBingo boosts email deliverability with Adestra

WhichBingo boosts overall email deliverability with Adestra’s support

WhichBingo, the UK’s leading bingo comparison site, needed to improve email inbox placement and reduce bounces, blocks, and spam issues. Because its gaming and gambling content was especially vulnerable to spam filters, prior email practices had left deliverability low, with inbox placement peaking at only around 40% before working with Adestra.

Adestra carried out a deliverability audit and guided WhichBingo through changes to email structure and data management, including SPF/DKIM validation, better domain handling, segmentation, and content adjustments. As a result, WhichBingo cut spam rating from 3.1 to 0, reduced bounces from up to 969 a month to just 5–10, lowered blocks from 252 per email to 0.3, and increased deliverability to 96%–99%.
