  • The 7 best transactional email services for developers in 2023
    Sparkpost. Good deliverability and a robust set of analytics tools make this a solid choice. - Source: dev.to / 7 months ago
  • What to do about outbound emails customers and vendors don't get?
    One of our staff was following up on orders to vendors via phone, and several said they didn't get our email with the PO. Someone said that sparkpost.com, Netsuite's email sender, was blacklisted. Blacklistings are hard (for me) to track down, especially since they clear up quickly. But blacklistings can trump most client's SPF/DKIM/whitelist guards. We are getting pushed by management to help ensure... Source: over 2 years ago
  • Post STMP Email Log Error
    Yes pretty much. In theory, you could use godaddy directly but sending emails through your web host is not something you want to do (They won't help much other than telling you to live with it). For better delivery of emails, you need transactional email providers. Not sure of your budget but my top choices are mandrillapp.com, sparkpost.com and sendgrid.com (in that order).

  • 💰 My Frugal Indie Dev Startup Stack
    The final note I'll make is that I've hand-rolled a few additional features that people are normally paying for. For example, I don't use Mailchimp or any tool like that — I send my marketing mail straight via Sendgrid. I dont use customer.io for my email sequences — even though it's very good — because I was able to just build my own email sequencing system. Time will tell whether I end up needing to replace my... - Source: dev.to / over 1 year ago
