I’m facing issues with my bulk emailing, as a lot of messages are bouncing back. It appears that the shared IP addresses from my current email provider, MailGun, are frequently blacklisted, primarily affecting deliveries to Google and Microsoft users, who represent a large segment of my clientele. Unfortunately, I can’t afford dedicated IP addresses, and MailGun hasn’t provided a viable solution for the problem. Are there any other email service providers out there who offer better success rates for bulk emails sent from shared IPs? I appreciate any advice or experiences you can share!
Amazon SES fixed my deliverability issues completely. Their shared IP pools stay clean because they’ve got automatic reputation management that blocks bad senders from messing things up for everyone else. Plus they’ve built solid relationships with Google, Microsoft, and other major ISPs.
My bounce rates dropped big time within a few weeks, especially with Gmail and Outlook. And you only pay for what you actually send - no monthly fees.
You’ll need to handle the SMTP setup yourself or use their SDK, but the docs are good and support responds quickly when you need help.
Finding another email provider won’t solve this. You need automated switching between multiple providers when deliverability tanks.
I built this exact setup for our marketing team last year. We were constantly fighting bounce rates and blacklists. Instead of manually switching providers and crossing our fingers, I automated the whole thing with real-time delivery monitoring.
When bounce rates hit our threshold on one provider, it automatically routes new sends through backups. Also handles list cleaning, instantly removes bounced emails, and manages authentication across all platforms.
Saved us hours every week and kept delivery rates above 95%. No more babysitting campaigns or panic switching when shared IPs get flagged.
You can build this without coding using workflow automation. Connects to SendGrid, Amazon SES, or whatever backup providers you want.
The real problem isn’t picking the right provider - it’s that you’re always reacting instead of preventing issues.
I dealt with this exact mess two years ago. We’d find a provider, everything worked great for weeks, then BAM - shared IPs got trashed by other users and our campaigns died. Switching providers every few months sucked.
What actually fixed it? I built an automated system that watches deliverability across multiple providers in real time. When one starts showing high bounces or blacklist problems, it automatically switches to clean backup providers.
It also handles list cleaning automatically - bounced emails get removed instantly so they don’t keep killing your sender rep. Plus it rotates through different IP pools and manages auth records across all your backup services.
Instead of playing whack-a-mole, you get steady delivery rates because bad IPs can’t nuke your whole operation.
You can build this without coding. Just connect your email providers through automated workflows that watch delivery metrics and switch routes when things tank.
brevo (formerly sendinblue) fixed my issues too! their ip reputation mgmt is really solid. noticed way fewer bounces with outlook after switching over. plus, their pricing is pretty good and setup was easy peasy.
mailchimp fixed my bulk email issues too. their shared IP pools are well managed and bad senders are isolated. been using it for 8 months, and my gmail delivery rates jumped up compared to mailgun.
ConvertKit fixed my deliverability issues with MailGun last year. They build their shared infrastructure specifically for content creators and marketers, so they’re way stricter about sender standards than transactional email providers. My Microsoft delivery rates jumped from 20% bounces to under 5% in the first month. The platform cleans your lists automatically and dumps problematic addresses before they trash your sender reputation. Their deliverability team watches IP health and pulls good senders away from compromised pools. Pricing’s fair for smaller volumes, and the analytics are solid for tracking improvements.
I switched from MailGun to SendGrid about six months ago because of the same bouncing problems. My deliverability got way better - bounce rates dropped from 15% to 3%. SendGrid handles their shared IPs much better. They watch sender reputations and isolate bad senders so they don’t mess things up for everyone else. Setup was easy, and their authentication helped my sender rep even more. I’m sending 50k emails monthly now with barely any blacklisting issues from the big providers. Their free tier works for smaller volumes, and paid plans are still cheaper than MailGun.
I transitioned from MailGun to SendGrid around eight months ago after facing similar issues with deliverability on shared IPs. I noticed a significant improvement in my email bounce rates within a few weeks, dropping from 15% to around 4-5%. SendGrid manages their shared IP pools much more effectively, and their reputation monitoring is far superior. Additionally, their pricing is reasonable for moderate email volumes. Their onboarding process was particularly beneficial; they assessed my email practices and offered tailored advice that helped improve my results. It’s definitely a viable option if you prefer not to invest in dedicated IPs.
postmark’s been rock solid lately. their shared pools stay cleaner since they focus on transactional emails instead of marketing blasts. my gmail delivery rates are way better than the mailgun nightmare i dealt with before.
