Robust emailing with PMTA We have partnered with Spartpost ( PMTA) since 2014. We send multiple emails in millions to our end clients. And with sparkpost we need not to worry about emails. Support team is also very prompt and resolves our concerns immediately. Thank you Sparkpost.

We barred them! They need to clean their act up! Over a long period we've frequently noted .sparkpostmail.com as the sender host for persistent spammers... which tells us the 'service' is basically unpoliced; undermining the credibility of legitimate users! This has been getting worse in the last year or so! - So frequent is the annoyance that we now BAR all email which has the string .sparkpostmail.com in any header via a Cpanel filter! I'd think twice about using this 'service' unless you want to find your messages trashed along with the Nigerian Princes, 'one weird tricks' and shonky viagra sales.

Port25 renewal process and is top notch. Port25 support team has always been top notch. Seems this trend has also moved to renewals. The new renewal team (or new for me) reached out to me, extended our license for a short period without me asking in order to accommodate the US Mail and has strong follow up. We’ve used the product for years and always had great product performance and continual improvement. The new focus on renewal process is a sign that this software firm is applying best practices to all areas of operation. Bravo!
