Jens, if you send a lot of emails, this will trigger Google to "look" at the account to see if it's a spam email account and can get the inbox shutdown. Google just went through a huge change last month that got a lot of domains shut down. Be careful sending a lot of emails and 20-25 is now a lot. Check Jays's latest video on his findings from over the last month. https://www.skool.com/lead-gen/cold-email-just-changed-again?p=52d26688 His Master Class will go into a lot of the reasoning and also shows you how fast things change in this space as it's only 7 months old and the email limits and suggestions for providers have already changes. Instead of the goal being "How many emails can I send?" It should be "How many emails can I send and not get marked spam or promotional AND make it so the recipient will read and respond positively?"

@Mishall Rashid Yeah, it's not a "conversation" if you give it the right prompt. The info is SOOO much better. I've watched a lot of videos with HUGE prompts, and while they are great and needed for what was being done, you don't always have to go that extreme (unless it's for production).

@Max Khalus Yeah, my TAM is very constrained. It's more of enrichment for the leads and finding the right connections. I'm thinking that the mode(s) I come up with to do this will just get bigger and more detailed as I work it out and will be low number of models. That's why, after the input I've received (though not many) is leading me to just stay with n8n. Plus, I'm a developer at heart, making it easy isn't as needed. Having more power... umm ahh... yup that's they way.

@Serena McDonald Since we sell to only ServiceNow customers, our TAM is limited by those who use ServiceNow. Also our target market is mostly Federal and larger organizations, further limiting the smaller TAM.

@Elsa Z Do the same thing I did for your messages. Check your Bell at top of the screen :)

@Serena McDonald Glad for you to join me here

First, that sucks! This thread took me by surprise so I did a little research on the issue. And it looks like it's a combination of things going on. Here is the summary: Google made a major push against spam and mailbox abuse in August–September 2025. Their August 2025 spam update was broad, fast, and hit both websites and email deliverability hard, especially for anyone using automated tools or “warmup” mailboxes. This update targeted both classic spammers and legitimate outreach users, wiping inboxes and causing sudden drops in deliverability. There’s confirmation that Gmail is specifically clamping down on automated warm-up services due to the risks of spam, abuse, and fake sender reputation. Manual warmup (real emails, slow ramp) is now the safest play.​ - The August 2025 spam update finished rolling out in late September and impacted lots of “safe” senders. - Google’s new AI filters are stricter, with lower complaint thresholds, stronger authentication requirements, and rate limiting on new/inactive domains. - Many warmup providers (like Instantly, GMass, Woodpecker) have been forced to shut down or switch away from API-based warmup for Gmail altogether. If your inboxes were affected, it’s probably part of a much wider sweep. Manual, human interaction is essential now—Google is actively blocking or removing anything that looks automated or “spammy,” even if coming from paid warmup tools.​

@Michael Ramirez @Jay Feldman just posted a new video on the issue and how to move to Microsoft https://www.youtube.com/watch?v=vfizBrte25s
