"Very happy with the results and service that Allegrow has provided"
5/5
What do you like best about Allegrow?

Very happy with the experience and results we are seeing from Allegrow! Over a period of about 30 days, we have seen an increase in deliverability from about 85% to above 90%. Our Google domain reputation also increased from Bad to High in that same period. The team at Allegrow is very quick to help and respond to any needs that we may have. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

It can sometimes be difficult setting up mailboxes. We use Office365 products bought through GoDaddy, and that has provided its own host of challenges. The team at Allegrow has been very helpful with the issues we've experienced, but the steps to take can be intimidating. Review collected by and hosted on G2.com.

"Email deliverability went from ugly to great"
5/5
What do you like best about Allegrow?

It actually worked. Within 2 months we went from 20% of our emails going to spam to only 4% Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

There are random emails in your inbox, but there really isn't a way around this for it to work and you can setup email filters to organize. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

I don't dislike anything about it. Setting it up was a process, but well worth the effort. Review collected by and hosted on G2.com.

"Peace of Mind and Great Results"
5/5
What do you like best about Allegrow?

Having used various email deliverability/warm-up tools prior to Allegrow, I can safely say that Allegrow is my favourite.

We have seen increased open rates and decreased spam rates. Overall, it gives great peace of mind especially when send a lot of emails.

Also excited to explore the content feature. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

One admin is the only downside at the moment. I would like to have both myself and our sales ops lead on there but this should be an easy fix as they grow.

Overall, that's the only one. Review collected by and hosted on G2.com.

"Our spam rate has improved and we're landing in more inboxes!"
5/5
What do you like best about Allegrow?

Thanks to the team at Allegrow we now have great structure to our emails. The team were really responsive and the time we worked with them helped us get a better understanding of what we should be focussing on when it comes to outbound emails in order not to land in spam. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

The set-up process is a bit lengthy to get it up and running but it's definitely worth it once you get there so it's worth the upfront time. Everything else was easy to navigate. Review collected by and hosted on G2.com.

"Best Deliverability Product!"
5/5
What do you like best about Allegrow?

The platform is extremely easy to use and is by far the best deliverability software on the market. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

I can't think of anything that I dislike about the product Review collected by and hosted on G2.com.

"Forget about your cold email deliverability problems"
5/5
What do you like best about Allegrow?

Allegrow's team has great in-depth insights about email deliverability. They were happy to provide expert advice on how we have to go about running cold email campaigns without damaging our email reputation. They know what they're doing. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

Nothing so far to say. They go above and beyond what you pay for, so I don't think there's really anything on their part that needs improvement. Just go for them. Review collected by and hosted on G2.com.

"Highly responsive team, has made a difference to our bounce rates."
5/5
What do you like best about Allegrow?

The team is very responsive via Chat and easy to set up. We needed the service mainly because .co. domains seem to be treated a bit more suspiciously in our instance and we wanted to ensure that we could get the delivery rates. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

More on how the system works, but it can be a bit confusing when you have a large email load to work out the best way to deal with allegrow mechanism emails. These are essential for how it works, I guess it's just the nature of the thing. Review collected by and hosted on G2.com.

"Great warmup tool!"
4.5/5
What do you like best about Allegrow?

After using various other warmup tools, Allegrow is by far the best. Their sequences are realistic and this has ultimately meant that as a team, we have seen bounce rates drop across all email accounts. Highly recommend. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

None so far. Some of the team complain their email sequences are too realistic ;) Review collected by and hosted on G2.com.

"The best email warm tool I've used, by far."
5/5
What do you like best about Allegrow?

I've used several email warming tools in the past, and I have to say that Allegrow is by far the most advanced and comprehensive I've used so far. My open rates have steadily moved up over the last few months, and overall I'd say it is a great tool that should be in any sales organization's toolbox. Review collected by and hosted on G2.com.

What do you dislike about Allegrow?

My only annoyance is the fact we have to leave some of the warm-up emails in our inbox. With that said however, it's really a minor grievance and I understand why the requirement exists, as it does enhance your mailbox's deliverability. It's just tough when you're used to reaching "inbox zero" every day. But again… That's the only gripe that I have, and it's definitely minor. I highly recommend this tool to anyone who needs to ensure their email deliverability remains high! Review collected by and hosted on G2.com.
