Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Poor Email Sender Reputation

Cold outreach emails consistently land in spam or get blocked due to poor sender reputation, misconfigured authentication, and dirty contact lists, killing reply rates and pipeline.

In their words

We are unable to access the admin console, make adjustments to email white/black lists, setup new clients in portal or new users under domains.

our email data quality has been trash lately - lots of bounces from Apollo

r/AiAutomations on Reddit

my boss is already on my case about email deliverability so i really need to figure this out before next quarter

r/SideProject on Reddit

our bounce rate is killing us. we're hitting like 8-10% bounces wich is destroying our sender reputation

r/AiAutomations on Reddit

the emails i was pulling had maybe a 12% bounce rate which is way too high when youre sending from one domain

r/micro_saas on Reddit

Hubspot stopped the send part way through because the bounce rate was nearly 8%.

if your open rates are below 40% on cold email, its probably not your copy. its probably your setup.

r/SaaSMarketing on Reddit

Some of our lists are getting stale (6+ months old) and we're seeing more hard bounces even after verification.

r/DigitalMarketing on Reddit

is there a reliable way to see if your domain blacklist situation is real? and if it is, how long does it take to get delisted?

r/EntrepreneurRideAlong on Reddit

Months 1 and 2 I was also sending too fast before warmup was done. That compounded the bounce rate problem.

r/b2b_sales on Reddit

We almost issued revised drawings based on instructions that never came from our client

r/architecture on Reddit

the domain got a bad reputation and the emails went to spam. I did not notice this for a while.

r/EmailOutreach on Reddit

while following up by phone with leads I'd emailed, multiple people told me my messages went straight to spam. I had no idea

Cold email senders

Where they talk

  • r/Emailmarketing
  • r/Coldemailing
  • r/b2bemailing
  • r/email
  • r/SaaS
  • r/gtmengineering
  • r/MailChimp
  • r/DigitalMarketing

Tools they use today

  • Apollo
  • Prospeo
  • Instantly
  • Mailchimp
  • Smartlead
  • Gmail
  • Hunter
  • ZeroBounce

Why those fall short

  • no safeguard against similar addresses
  • Portal down 72+ hours; support gives no info or timeline
  • no SPF/DKIM/DMARC setup, no warmup, fresh domains
  • verification alone doesn't stop decay; Apollo data inconsistent, valid addresses still bounce
  • Free checkers show different results; no reliable view of which lists matter.
