It repairs and protects sender reputation at the domain and IP level, warms up new domains and IPs on an adaptive schedule, and shows where messages actually land through inbox placement testing across Gmail, Outlook, Yahoo and other major mailbox providers. Live blacklist monitoring and deliverability alerts surface problems as they develop rather than after a campaign underperforms, and an ML-modeled sender score makes reputation measurable week to week. InboxAlly runs alongside the stack you already have. It works with any ESP, SMTP service or custom sending infrastructure - including Mailchimp, SendGrid, Amazon SES, Brevo, Klaviyo, HubSpot and Instantly - with no migration and no change to how you send, and without handing over your sending credentials. A REST API and native integrations support programmatic setup, and separate sender profiles let agencies and multi-brand senders manage many domains side by side. Based in New York, InboxAlly supports email marketers, agencies, cold outreach teams, SaaS senders and deliverability consultants, from a single domain to enterprise sending programs. Every plan includes a dedicated customer success manager and 24/7 live support, and evaluation starts with a 10-day free trial that requires no credit card. 136 Ratings Visit Website Bluehost Bluehost is a web hosting provider that offers reliable hosting services for websites, blogs, and online businesses.

About What is Postfix? It is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program. Now at Google, Wietse continues to support Postfix. Postfix runs (or has run) on AIX, BSD, HP-UX, IRIX, LINUX, MacOS X, Solaris, Tru64 UNIX, and other UNIX systems. It requires ANSI C, a POSIX.1 library, and BSD sockets. Postfix attempts to be fast, easy to administer, and secure. The outside has a definite Sendmail-ish flavor, but the inside is completely different. Multiple SMTP deliveries over the same TLS-encrypted connection. This reuses the existing tlsproxy(8) and scache(8) services. MySQL stored procedure support. Gradual degradation: in many cases a Postfix daemon will log a warning and continue providing the services that are still available, instead of immediately terminating with a fatal error. Postfix can set the execute bit on a queue file. If this does not work, then no mail will ever be delivered.

Pros & Cons from Real Users Pros Personalized service. Fast responses to questions and any issues. Good value. Good technical features. Great technical support. Cost savings after Rackspaces significant monthly increase Good support, Ryan has been great! Ease of transition, mostly an administrative transition We had some concern as many did with the Rackspace price increase looming around the corner. I did a lot of research and when i found out that we could migrate to Greatmail without having to reconfigure ANYTHING, I was skeptical. But then I reached out to Ryan Hess who walked me through the process and it truly was that easy! in less than an hour, the migration was complete with no down time whatsoever. The only change, literally, is who we pay our (less expensive) bill to and who we reach out to for support. Thanks, Ryan and the Greatmail team! We've been using Rackspace email for 3 years. Suddenly Rackspace demanded 3 times (!!!) as much per-mailbox so we had to look for a new Provider. After doing some serious research we decided to try Greatmail. We contacted their support to migrate our mailboxes as usual but they offered us even better solution: we KEEP our existing Rackspace setup (with all mailboxes and settings) but we start paying old price to Greatmail as a re-seller instead of paying new price to Rackspace directly. So we signed for a new account with Greatmail and transferred our existing email domain to that new account. Next we canceled our old Rackspace account and avoided the ridiculous 3 times price increase. The whole process took less than an hour and we did NOT have to re-configure any email clients. ZERO DOWNTIME ! Excellent professional and timely support. Outstanding customer support and exemplary technical functionality. Personal interaction regardless of subject with perfect results - every time! Cons It is a small shop, which is also a positive, but can sometimes feels a little small business. No negatives so far...Ryan has been responsive and a big help! No cons whatsoever. Only regret is not switching earlier than we did, as others have stated. No Cons. We should have switched to Greatmail earlier. No issue at all. There are no outstanding concerns of any kind in our technical or personal relationship.	Pros & Cons from Real Users Pros 1. Easy to deploy. 2. Easy to customize at an intense level. 3. Easy to integrate with DKIM and DMARC. 4. Various workaround available. 5. Lightweight to operate. Cons Sometimes troubleshooting deliveries can be troublesome. Integration with Social media like LinkedIn and Facebook inside Postfix is not possible yet.
