I own a small company where we monitor fridges and launch alert emails & SMS when a threshold is reached.<p>We send about 1 mail per day, with bursts to 10-50 if there are alerts to send, but this is a very small amount of mail.<p>I tried the free sendgrid offer, but their IP is blacklisted with spamhaus... Their pro offer is more than $20/month which is way above our hosting costs.<p>Considering that we only send a very few amount of mails, do you know of a reputable SMTP/email sender that could be affordable for us ? Say, no more than $5 / month?
