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 Maropost Marketing Cloud Automate the moments that move customers to buy.

Pros & Cons from Real Users Pros Ok, thanks for the opportunity, be honest, these are my feedback after useing, please check below. first pro: 80% successful rate to find right email. second pro: most of time input first name and family name with company website, i can find right email. Emails actually get delivered unlike some other email marketing services and transactional email services we were using prior to SendGrid. Almost nothing. The system is too barebones, can't put emojis in emails, very little actual customization, other platforms are much better. I did like that the software was easy to use. It had a very user-friendly interface and made things easy to navigate through. Uploading contacts was a streamlined process. Sendgrid allows our company to send updates to a vast array of consumers through email. The credentials built through Sendgrid software allow our emails to not end up in the Junk Folder. Cons First con: if a person has many job positions at different companies, you only can obtain the first company information and existing person emails. Second con: it can't link with more social channels, like Twitter or Instagram and can't grab email in pictures and PDF files, also many information shows in Google but can't be found here. Third con: RocketReach can find the right email but usually GetEmail can't. Fourth con: the cost is high for monthly, and can't get free credits most of times. That's all the cons I found, i have been using this tool for more than one and a half years, anyway, thank you very much, hope your team can improve and do better. No cons for our use cases. Does everything we need it to do. First of all the service didn't work. The campaigns wouldn't be sent at all and I had to call customer support. EVERY TIME. And it would take time, hours DAYS, every time. So we lost a lot in proper campaign timing, leads would get cold. We lost ROI there. I didn't like that their shared IP still got bad ratings. I used a few of their competitors before this, and was getting much better open rates using the same emails on the other platforms. I needed a lot of help setting up my account. It would be helpful to have a more user-friendly set up.	Pros & Cons from Real Users Pros When I got stuck, the chat team was right there to bring me back to reality and even credited the second submission of my validating list. The chat support is excellent. I had questions and was able to get them answered fast. Plus the live chat rep offered me a discount on my initial purchase. Worked great! Quick support team. Helpful policies. Just started using this tool for my consultancy; apart from this I have been using this in my past organization for more that a year. Since I use ZeroBounce, I get a better inbox rate because I am sending only to valid email addresses and ZeroBounce are excellent to get the best verification. The necessity for email validation has never become so apparent in keeping IP and Domain reputations in good standing. Reducing or down right eliminating the amount of bounced email goes a long way in ensuring that the sender isn't looked negatively upon by email ISPs. The fact that Zero Bounce offers an API, makes it much more streamlined for the likes of automated email campaign generation, and email list sanitation programs we use on a daily basis. Cons A couple of features weren't so easy to figure out. But I guess I should have read the instructions through a second time. Nothing to note here. I have not started actually using the service yet. Know that my review is mainly about the buying and signup process. Catch-all status is kind of road blocking. Grey listed status- it defines verified and invalid on Excel sheet but not with single email address validator. Sometimes it is lagging but not big deal they resolve issues very quickly. So far, not many negatives to speak on. Would prefer to use the API instead of the bulk email upload tool on the website.
