(Disclaimer: I run Buttondown, which is an email-inflected product. I also have a comparison guide of various MTAs here — https://buttondown.email/comparison-guides/esps — and will add Plunk!)

Nuances of self-hosting aside, I'd recommend caution looking at that pricing pane.

The disclaimer is:

> Calculated based on the plan that best matches the features of Plunk at 2500 emails per month.

And the author then cites prices of $0.001/email for Plunk and $0.013/email for Sendgrid.

I am neither a user or fan of Sendgrid but that feels like disingenuous anchoring. Sendgrid's free plan is 100/day; if you want to eliminate the free plan entirely and just focus on their cheapest paid option, it's $19.95 for 50K emails — or $0.000399/email, cheaper than Plunk's sticker price.

It's not entirely obvious to me how that $0.013 was even calculated ($0.013 * 2500 = $32.50). Either way, be sure to spot-check against live sticker rates before making a decision there.
