AutoSPF automatically maintains updated SPF records for businesses. Our solution compresses the number of DNS lookups in SPF records, which will improve the delivery rate of emails, allow for DMARC alignment and help with compliance. ## AutoSPF Reviews ### 1. AutoSPF Flattens SPF Records Seamlessly & Keeps Changes Logged - I am quite pleased with the product **Rating:** 5.0/5.0 stars **Reviewed by:** Peter J. | President, Small-Business (50 or fewer emp.) **Reviewed Date:** March 10, 2026 **What do you like best about AutoSPF?** It does what it promises to do, and does it very well. I appreciate that it keeps a log of changes made, which prevents many mistakes. A client's SPF record would have way too many lookups, but AutoSPF makes that problem go away. The length of the SPF record is typically not the issue; it's the amount of lookups in the record that are. AutoSPF "flattens" the record, automatically expanding the defined lookups to IP addresses or ranges. And it auto-updates the record when the un-flattened lookups change. BTW I discovered AutoSPF in a web search several years ago. I do not recall any other product that I evaluated, but the price seemed right (still is), and I haven't looked back. **What do you dislike about AutoSPF?** Minor: You can comment on each entry, but the saved comments are not shown in the portal unless you click on them. Not a big deal, but this should be fixed. Otherwise there's a bit of a learning curve, but IMO it's well worth it. **What problems is AutoSPF solving and how is that benefiting you?** It does exactly what they say it does, and I haven’t seen any outages that would affect its performance. The price I paid feels quite reasonable for what it is and what it delivers. ### 2. Helped us go beyond capacity. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** July 31, 2025 **What do you like best about AutoSPF?** AutoSPF did exactly as described, it helped us get past our 10 lookup limit. Afterwards, we hit another limit regarding overall capacity and when contacted, they quickly provided us with a new solution to eliminate capacity issues entirely going forward, so now we can add as many SPF records as needed. They also provided us with a personalized support video explaining their new method in its entirety using our instance as the example, which helped us to better understand their solution. **What do you dislike about AutoSPF?** Honestly, a few billing errors were the biggest issue, but the company worked diligently to helps us determine where the issue was and get it resolved. This team really is one of the better vendors we work with. **What problems is AutoSPF solving and how is that benefiting you?** SPF capacity limitations ### 3. Great service and great support **Rating:** 5.0/5.0 stars **Reviewed by:** Greg F. | Mid-Market (51-1000 emp.) **Reviewed Date:** July 26, 2023 **What do you like best about AutoSPF?** AutoSPF was easy to initially set up on our own and a great cost effective entry into spf flattening. Needed our first support assistance today and got great response including a video demonstrating the issue I was trying to solve, a quick fix, and more detailed followup. **What do you dislike about AutoSPF?** I haven't found anything yet that I dislike. **What problems is AutoSPF solving and how is that benefiting you?** Getting our spf record down within limits. With some of the external services we use, flattening became a must. ### 4. Simple Solution for a Large Problem **Rating:** 5.0/5.0 stars **Reviewed by:** Glenn G. | Enterprise (> 1000 emp.) **Reviewed Date:** June 02, 2023 **What do you like best about AutoSPF?** Simple to use and easy to deploy! Moreover, administration and maintenance of our SPF record is super simple. **What do you dislike about AutoSPF?** Nothing. This product is an absolute must have for email administrators. **What problems is AutoSPF solving and how is that benefiting you?** This tool help us resolve the limitation with SPF lookups (10) ### 5. Robust and useful product with incredible support **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Insurance | Mid-Market (51-1000 emp.) **Reviewed Date:** January 12, 2022 **What do you like best about AutoSPF?** AutoSPF is a simple tool to solve a significant problem. It does it so very well without any issues. Additionally, the support is very professional and goes above and beyond to help resolve any email-related issues for their customers. **What do you dislike about AutoSPF?** We found nothing to dislike about the service. **What problems is AutoSPF solving and how is that benefiting you?** Upon discovering we could not send out-of-office messages, we checked if there was an issue with our AutoSPF settings. After raising a ticket, we hopped on a Zoom call with support and, after a few minutes, discovered that our DKIM records were not set up correctly. AutoSPF support provided us tips on how to resolve the problem, which was far beyond the scope of their service. Not long after, everything was functioning again as expected. AutoSPF’s fantastic support saved us hours, if not days, of further troubleshooting time by knowing right away what the problem was. ### 6. Great product with the BEST support on the Planet! **Rating:** 5.0/5.0 stars **Reviewed by:** Chris C. | Office 365 Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** June 24, 2021 **What do you like best about AutoSPF?** The ease of use of the product really let's us "set it and forget it" when it comes to SPF management. The product support - specifically with Brad Slavin is top notch. He spent over a half hour helping me find information and fix an issue that had nothing to do with his job. His technical knowledge of not only his product but also how to get answers and solutions for other real-world issues is unmatched. **What do you dislike about AutoSPF?** We really like everything about the product and its support. **What problems is AutoSPF solving and how is that benefiting you?** SPF management had become a bit overwhelming with the rapid increase of third party companys sending on our behalf. The limited number of lookups allowed made it very difficult to manage. AutoSPF takes care of all of that. Easiest solution ever. ### 7. AutoSPF 10/10 **Rating:** 5.0/5.0 stars **Reviewed by:** Jacob H. | IT Analyst **Reviewed Date:** January 05, 2022 **What do you like best about AutoSPF?** AutoSPF takes the hassle out of dealing with SPF records. You use the dropdown list to select the company to include, save, that's it! **What do you dislike about AutoSPF?** So far, I haven't found anything about AutoSPF that I dislike. **What problems is AutoSPF solving and how is that benefiting you?** I had too many lookups, and I needed a quick, easy, and inexpensive way to solve this. With this service, I no longer have to worry about it. ### 8. Fantastic Help on SPF **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Construction | Small-Business (50 or fewer emp.) **Reviewed Date:** July 29, 2021 **What do you like best about AutoSPF?** A colleague of mine told me that my email was hackable because of an SPF error she received. I didn't even know anything about authenticating SPF for email at all. I got in touch with Brad, and he was simply amazing. He broke everything down in easy steps and was able to solve my problem so fast. My small business is now protected and I couldn't have done it without him. He went above and beyond to help me. **What do you dislike about AutoSPF?** There is nothing that I do not like about this. **What problems is AutoSPF solving and how is that benefiting you?** My email deliverability was being affected by the SPF fail and the colleague we sent the email to was worried we could be hacked like they were. ### 9. Best support experience of my life **Rating:** 5.0/5.0 stars **Reviewed by:** Jay H. | Senior Director, IT, Mid-Market (51-1000 emp.) **Reviewed Date:** March 02, 2021 **What do you like best about AutoSPF?** Customer service is exceptional. We were getting bounced emails with SPF errors but when we checked our SPF record it came back fine. We had no idea how to troubleshoot but opened a priority ticket and had a Zoom invite within minutes and had the problem solved with 30 minutes. **What do you dislike about AutoSPF?** No dislikes. We haven't used the product long but it works, the price is great, and support is awesome. **Recommendations to others considering AutoSPF:** The pricing is fantastic. We were paying significantly more for SPF flattening from our previous vendor. When we had a self-inflicted issue with email deliverability related to SPF, Brad quickly sent us a Zoom invite and walked us through the process. His knowledge was outstanding and he knew exactly what to do to fix the problem. The best part is none of the problems were with AutoSPF, the problems were with our MX record and some settings in O365. He could have easily said, "Your SPF record checks fine so there's nothing I can do," but he didn't. **What problems is AutoSPF solving and how is that benefiting you?** We have a lot of systems that need to send email on our behalf and we quickly ran out of room to add new systems. AutoSPF solved that. ### 10. Fantastic product, great service, wonderful support. **Rating:** 5.0/5.0 stars **Reviewed by:** Jared M. | Director of Engineering, Small-Business (50 or fewer emp.) **Reviewed Date:** February 03, 2021 **What do you like best about AutoSPF?** AutoSPF solved an issue for us that would have required a pretty sloppy manual hack that would also have been prone to, essentially, getting out of date. For an extremely fair price, AutoSPF takes care of the issue, and I don't have to worry about it ever again. On top of that the support for this product is among the best I've experienced in the tech industry at large. I know these guys care, and they obviously know their stuff. If every company was this good, society would really be going places. **What do you dislike about AutoSPF?** Nothing thus far in terms of what it achieves for us. It works well and is incredibly simple to set up. **Recommendations to others considering AutoSPF:** If this is something you need for your spf records, I wouldn't hesitate to sign up. **What problems is AutoSPF solving and how is that benefiting you?** AutoSPF fixes an issue we had where we had too many DNS calls in our spf setup on AWS. This was potentially affecting some of our deliverability, and getting us back into the "healthy" range via AutoSPF eliminates this possibility. ## AutoSPF Discussions - [What is AutoSPF used for?](https://www.g2.com/discussions/what-is-autospf-used-for) - [View AutoSPF pricing details and edition comparison](https://www.g2.com/products/autospf/reviews/autospf-review-7689911?section=pricing&secure%5Bexpires_at%5D=2026-07-13+08%3A12%3A02+-0500&secure%5Bsession_id%5D=d5615b8d-0bdf-4557-a238-29065370fd95&secure%5Btoken%5D=e712678c7ce47dba74a171e17f4ddde54efb824f80a3f31c91666ad5926063c0&format=llm_user) ## AutoSPF Features **Diagnostics** - Account Overview - DMARC Alignment - Analytics **Compliance** - Policy Configuration - Alerts - Inbound Emails - Outbound Emails **Protection** - Threat Identifications - Threat Interception - Threat Removal - Integrations ## Top AutoSPF Alternatives - [Valimail](https://www.g2.com/products/valimail/reviews) - 4.5/5.0 (459 reviews) - [ZeroBounce](https://www.g2.com/products/zerobounce/reviews) - 4.7/5.0 (1,354 reviews) - [EasyDMARC](https://www.g2.com/products/easydmarc/reviews) - 4.7/5.0 (234 reviews)
