Changing email rules across providers is nothing new, albeit a recent ‘silent’ shift from Google can catch out unaware funds.
With investor emails still so popular and bad bot traffic on the rise, the frontier of email deliverability is more of a Wild West than ever. To add insult to injury, Gmail went live with what Google now counts as an ‘acceptable’ Spam-complaint rate without any announcement.
The change was quietly implemented in an update to Gmail’s Postmaster Tools API after the service had begun to roll out its “deliverability analysis” feature. This converts raw data in plain-language, in one example blankly stating “users signal they don’t want to get your email messages.” Harsh!
There are, though, numerics that fund managers must heed to avoid the trapdoors they will face should their communications be marked as Spam:
- 0.3% was the working ‘acceptable’ spam-complaint rate since Google’s 2024 sender requirements were actioned.
- As of July 2026, this is now 0.1%, a three-times stricter rule than what most email platforms (many built using Google’s original guidance) have been designed for.
- A new ‘indifference’ category (where recipients do not complain nor engage with an email) is a tracked warning flag rather than its past tag as a ‘non-issue.’
A sender’s reputation is greatly impacted by this change. Any outright Spam rejection is an emailing disaster, particularly prevalent for alternative managers who curate smaller prospective LP email lists to focus on high-value potential.
So, what does this mean for fund managers?
Such smaller lists makes hygiene and deliverability a more glaring issue compared to large mass-consumer focused managers who may update tens of thousands of retail subscribers. A few minor Spam complaints or ignored cadences will be disproportionately detrimental.
In that light, IRs and marketers have to take that 0.1% rate very seriously as the concrete ceiling and shift away from the thought that having zero complaints is all well and good.
Now that Gmail accounts for silence as strongly as it does responding criticism, outreach teams should re-address their contacts, weed out any that have not opened any emails, or have unsubscribed, to make sure complaint-handling workflows are cleared before any new performance update or monthly newsletter.
Where CRM “email blast” features are used, it is also recommended to revisit marketing operations with IT teams. They should be enabled with deliverability monitoring to see if authentications (SPF, DKIM, and DMARC) are being tracked accordingly, and therefore more likely to see future emails landing firmly in an allocator’s inbox. Before the next, potentially silent, update…
